厦门海沧大桥钢桥面铺装翻修设计说明1 概述厦门海沧大桥主桥为三跨连续全漂浮结构钢箱梁悬索桥，全长1104m，主跨648m，桥面宽31m，行车道宽2 14.75m，中央分隔带宽1.5m，钢桥面铺装面积为32568m2。

厦门海沧大桥桥面系为正交异性钢板，钢板厚度12mm。

大桥1999年通车，采用热熔型粘接剂加双层SMA的铺装结构，在2002年和2005年，都进行了全桥翻修。

2005年采用的铺装方案为：环氧富锌底漆+环氧粘结层+橡胶沥青砂胶+下层SMA+玻纤格栅+上层SMA+雾封层，使用效果较好，已经运行了五年，桥面铺装有了很大改善。

近两年来，由于超载车、重车以及车流量急速增多及SMA改性沥青铺装层逐年老化，进岛向重车道已出现较严重车辙和网状裂缝，为满足车辆日益增长的需要，保持良好路况，厦门路桥建设集团有限公司拟定在2011年对钢桥面铺装进行全面翻修，要求新铺装方案能够满足车流量日益增长的需要，推迟病害出现时间，确保铺装层的寿命至少6年路况优良。

受厦门路桥建设集团有限公司委托，在对原方案进行优化分析的基础上，综合我院的先进研究成果，开展厦门海沧大桥钢桥面铺装翻修施工图设计。

SPECIFICATION FOR SEAMLESS AND WELDED AUSTENITIC STAINLESS STEEL PIPESSA-312/SA-312M(Identical to ASTM Specification A312/A312M-95b except forclarified heat treatment requirements in5.2.2.)1.Scope1.1This specification covers seamless and straight-seam welded austenitic steel pipe intended for high-temperature and general corrosive service.NOTE1—When the impact test criterion for a low-temperature service would be15ft·lbf[20J]energy absorption or15mils[0.38 mm]lateral expansion,some of the austenitic stainless steel grades covered by this specification are accepted by certain pressure vesselor piping codes without the necessity of making the actual test.For example,Grades TP304,TP304L,and TP347are accepted by the ASME Pressure Vessel Code,Section VIII Division1,and by the Chemical Plant and Refinery Piping Code,ANSI B31.3,for serviceat temperatures as low as−425°F[−250°C]without qualification by impact tests.Other AISI stainless steel grades are usually acceptedfor service temperatures as low as−325°F[−200°C]without impact testing.Impact testing may,under certain circumstances,be required.For example,materials with chromium or nickel content outside the AISI ranges,and for material with carbon content exceeding0.10%,are required to be impact tested under the rules of ASME SectionVIII Division1when service temperatures are lower than−50°F[−45°C].1.2Grades TP304H,TP309H,TP309HCb,TP310H,TP310HCb,TP316H,TP321H,TP347H,and TP348Hare modifications of Grades TP304,TP309Cb,TP309S,TP310Cb,TP310S,TP316,TP321,TP347,and TP348, and are intended for high-temperature service.1.3Optional supplementary requirements are providedfor pipe where a greater degree of testing is desired. These supplementary requirements call for additional tests to be made and,when desired,one or more of these may be specified in the order.1.4Table X1.1lists the dimensions of welded and seamless stainless steel pipe as shown in ANSI B36.19. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.4771.5Grades TP321and TP321H have lower strength requirements for pipe manufactured by the seamless process in nominal wall thicknesses greater than3⁄8in.[9.5mm].1.6The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text,the SI units are shown in brackets.The values stated in each system are not exact equivalents; therefore,each system must be used independently of the bining values from the two systems may result in nonconformance with the specification.The inch-pound units shall apply unless the“M”designation of this specification is specified in the order.NOTE2—The dimensionless designator NPS(nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,”“size,”and“nominal size.”2.Referenced Documents2.1ASTM Standards:A262Practices for

Specification A530/A530M),3.1.10Specification number,and3.1.11Special requirements or any supplementary requirements selected,or both.4784.General Requirements4.1Material furnished under this specification shall conform to the applicable requirements of the current edition of Specification A530/A530M unless otherwise provided herein.5.Materials and Manufacture5.1Manufacture:5.1.1The pipe shall be made by the seamless or an automatic welding process,with no addition offiller metal in the welding operation.5.1.2“Welded pipe NPS14and smaller shall havea single longitudinal weld.Welded pipe of a size larger than NPS14may be produced by forming and welding two longitudinal sections offlat stock when approved by the purchaser.All weld tests,examinations,inspections, or treatments are to be performed on each weld seam.”5.1.3At the manufacturer’s option,pipe may be either hotfinished or coldfinished.5.1.4The pipe shall be free of scale and contaminating iron particles.Pickling,blasting or surfacefinishing is not mandatory when pipe is bright annealed.The purchaser may request that a passivating treatment be applied.5.2Heat Treatment:5.2.1All pipe shall be furnished in the heat-treated condition in accordance with the requirements of Table 2.The heat-treatment procedure,except for“H”grades, S30815,S31272,S31254,S32654,N08367,and N08904 shall consist of heating the pipe to a minimum tempera-ture of1900°F[1040°C]and quenching in water or rapidly cooling by other means.5.2.2All H grades shall be furnished in the solution-treated condition.For H grades,separate solution heat treatments are required for solution annealing;in-process heat treatments are not permitted as a substitute for the separate solution annealing treatments.A solution anneal-ing temperature above1950°F[1065°C]may impair the resistance to intergranular corrosion after subsequent ex-posure to sensitizing conditions in TP309HCb, TP310HCb,TP321,TP321H,TP347,TP347H,TP348, and TP348H.When specified by the purchaser,a lower temperature stabilization or re-solution anneal shall be used subsequent to the initial high temperature solution anneal(see Supplementary Requirement S6).PART A—FERROUS MATERIAL SPECIFICATIONS SA-312/SA-312M5.3Grain Size:5.3.1The grain size of Grade UNS S32615,as determined in accordance with Test Methods E112, shall be No.3orfiner.5.3.2The grain size of TP309H,TP309HCb,TP310H and TP310HCb,as determined in accordance with Test Methods E112,shall be No.6or coarser.5.3.3The grain size of TP321H,as determinedin accordance with Test Methods E112,shall be No.7or coarser.6.Chemical Composition6.1The steel shall conform to the requirements asto chemical composition prescribed in Table1.7.Product Analysis7.1At the request of the purchaser,an analysis of one billet or one length offlat-rolled stock from each heat,or two pipes from each lot shall be made by the manufacturer.A lot of pipe shall consist of the following number of lengths of the same size and wall thickness from any one heat of steel:NPS Designator Lengths of Pipe in LotUnder2400or fraction thereof2to5200or fraction thereof6and over100or fraction thereof7.2The results of these analyses shall be reportedto the purchaser or the purchaser’s representative,and shall conform to the requirements specified in Section6. 7.3If the analysis of one of the tests specified in 7.1does not conform to the requirements specified in Section6,an analysis of each billet or pipe from the same heat or lot may be made,and all billets or pipe conforming to the requirements shall be accepted.8.Tensile Requirements8.1The tensile properties of the material shall con-form to the requirements prescribed in Table3.9.Mechanical Tests and Grain SizeDeterminations Required9.1Transverse or Longitudinal Tension Test—One tension test shall be made on a specimen for lots of479not more than100pipes.Tension tests shall be made on specimens from two tubes for lots of more than 100pipes.NOTE3—The term“lot,”for mechanical tests,applies to all pipe of the same diameter and wall thickness(or schedule)which are produced from the same heat of steel and subjected to the same finishing treatment:(1)in a continuous heat-treatment furnace,or (2)in a batch-type heat-treatment furnace,equipped with recording pyrometers and automatically controlled within a50°F[30°C]range, the larger of:(a)Each200ft[60m]or fraction thereof or,(b) That pipe heat treated in the same batch furnace charge.9.2Flattening Test—For material heat treated ina batch-type furnace,flattening tests shall be made on 5%of the pipe from each heat-treated lot.For material heat treated by the continuous process,this test shall be made on a sufficient number of pipe to constitute 5%of the lot,but in no case less than two lengths of pipe.9.2.1For welded pipe a transverse-guided face bend test of the weld may be conducted instead of a flattening test in accordance with the method outlined in the steel tubular product supplement of Test Methods and Definitions A370.The ductility of the weld shall be considered acceptable when there is no evidence of cracks in the weld or between the weld and the base metal after bending.Test specimens from5%of the lot shall be taken from the pipe or test plates of the same material as the pipe,the test plates being attached to the end of the cylinder and welded as a prolongation of the pipe longitudinal seam.9.3Hydrostatic Test—Each length offinished pipe shall be subjected to the hydrostatic test in accordance with Specification A530/A530M,unless specifically exempted under the provisions of9.4and9.5.9.4For pipe whose dimensions equal or exceed NPS 10,the purchaser with the agreement of the manufacturer may waive the hydrostatic test requirement when in lieu of such test the purchaser performs a system test. Each length of pipe furnished without the completed manufacturer’s hydrostatic test shall include with the mandatory markings the letters“NH.”9.5Nondestructive Examination:9.5.1As an alternative to the hydrostatic test,and when specified by the purchaser,each pipe shall be examined with a nondestructive test in accordance with Practice E213,or E426.Unless specifically called out by the purchaser,the selection of the nondestructive electric test will be at the option of the manufacturer. The range of pipe sizes that may be examined by each method shall be subject to the limitations in the scope of the respective practices.SA-312/SA-312M1998SECTION II9.5.2The following information is for the benefitof the user of this specification.9.5.2.1The reference standards defined in9.5.2.2 through9.5.2.5are convenient standards for calibrationof nondestructive testing equipment.The dimensionsof these standards should not be construed as the minimum size imperfection detectable by such equipment.9.5.2.2The ultrasonic testing(UT)can be per-formed to detect both longitudinally and circumferen-tially oriented defects.It should be recognized that different techniques should be employed to detect differ-ently oriented imperfections.The examination may not detect short,deep defects.9.5.2.3The eddy-current testing(ET)referencedin this specification,(Practice E426),has the capabilityof detecting significant discontinuities,especially the short abrupt type.9.5.2.4A purchaser interested in ascertainingthe nature(type,size,location,and orientation)of discontinuities that can be detected in the specific application of these examinations should discuss this with the manufacturer of the tubular product.9.5.3Time of Examination:9.5.3.1Nondestructive testing for specification acceptance shall be performed after all mechanical processing,heat treatments,and straightening opera-tions.This requirement does not preclude additional testing at earlier stages in the processing.9.5.4Surface Condition:9.5.4.1All surfaces shall be free of scale,dirt, grease,paint,or other foreign material that could inter-fere with interpretation of test results.The methods used for cleaning and preparing the surfaces for exami-nation shall not be detrimental to the base metal orthe surfacefinish.9.5.4.2Excessive surface roughness or deep scratches can produce signals that interfere with the test.9.5.5Extent of Examination:9.5.5.1The relative motion of the pipe and the transducer(s),coil(s),or sensor(s)shall be such thatthe entire pipe surface is scanned,except as in9.5.5.2.9.5.5.2The existence of end effects is recog-nized,and the extent of such effects shall be determinedby the manufacturer,and,if requested,shall be reportedto the purchaser.Other nondestructive tests may be480applied to the end areas,subject to agreement between the purchaser and the manufacturer.9.5.6Operator Qualifications:9.5.6.1The test unit operator shall be certified in accordance with SNT-TC-1A,or an equivalent recog-nized and documented standard.9.5.7Test Conditions:9.5.7.1For eddy-current testing,the excitation coil frequency shall be chosen to ensure adequate penetration yet provide good signal-to-noise-ratio.9.5.7.2The maximum eddy-current coil fre-quency used shall be as follows:On specified walls up to0.050in.-100KHz maxOn specified walls up to0.150in.-50KHz maxOn specified walls up to0.150in.-10KHz max9.5.7.3Ultrasonic-For examination by the ultra-sonic method,the minimum nominal transducer fre-quency shall be2.00MHz and the maximum nominal transducer size shall be1.5in.(a)If the equipment contains a reject noticefilter setting,this shall remain off during calibration and testing unless linearity can be demonstrated at that setting.9.5.8Reference Standards:9.5.8.1Reference standards of convenient length shall be prepared from a length of pipe of the same grade,size(NPS,or outside diameter and schedule or wall thickness),surfacefinish and heat treatment condi-tion as the pipe to be examined.9.5.8.2For Ultrasonic Testing,the reference ID and OD notches shall be any one of the three common notch shapes shown in Practice E213,at the option of the manufacturer.The depth of each notch shall not exceed121⁄2%of the specified nominal wall thickness of the pipe or0.004in.,whichever is greater.The width of the notch shall not exceed twice the depth.

condition,and at intervals not exceeding4h.More frequent standardiza-tion may be performed at the manufacturer’s optionor may be required upon agreement between the pur-chaser and the manufacturer.9.5.9.2The test apparatus shall also be standard-ized after any change in test system settings,changeof operator,equipment repair,or interruption due to power loss,process shutdown or when a problem is suspected.9.5.9.3The reference standard shall be passed through the test apparatus at the same speed and test system settings as the pipe to be tested.9.5.9.4The signal-to-noise ratio for the reference standard shall be2-1⁄2to1or greater.Extraneous signals caused by identifiable causes such as dings, scratches,dents,straightener marks,etc.,shall not be481considered noise.The rejection amplitude shall be ad-justed to be at least50%of full scale of the readout display.9.5.9.5If upon any standardization,the rejection amplitude has decreased by29%(3dB)of peak height from the last standardization,the pipe since the last calibration shall be rejected.The test system settings may be changed,or the transducer(s),coil(s)or sensor(s) adjusted,and the unit restandardized,but all pipe tested since the last acceptable standardization must be retested for acceptance.9.5.10Evaluation of Imperfections:9.5.10.1Pipes producing a signal equal to or greater than the lowest signal produced by the reference standard(s)shall be identified and separated from the acceptable pipes.The area producing the signal may be reexamined.9.5.10.2Such pipes shall be rejected if the test signal was produced by imperfections that cannot be identified or was produced by crack or crack-like imper-fections.These pipes may be repaired per Sections11 and12.To be accepted,a repaired pipe must pass the same non-destructive test by which it was rejected,and it must meet the minimum wall thickness requirements of this specification.9.5.10.3If the test signals were produced by visual imperfections such as:(a)Scratches;(b)Surface roughness;(c)Dings;(d)Straightener marks;(e)Cutting chips;(f)Steel die stamps;(g)Stop marks,or;(h)Pipe reducer ripple.The pipe may be accepted based on visual examina-tion provided the imperfection is less than0.004in.[0.1mm]or12-1⁄2%of the specified wall thickness (whichever is greater).9.5.10.4Rejected pipe may be reconditioned and retested providing the wall thickness is not decreased to less than that required by this or the product specifica-tion.The outside diameter at the point of grinding may be reduced by the amount so removed.To be accepted, retested pipe shall meet the test requirement.9.5.10.5If the imperfection is explored to the extent that it can be identified as non-rejectable,the pipe may be accepted without further test providingSA-312/SA-312M1998SECTION IIthe imperfection does not encroach on the minimum wall thickness.9.6Grain Size—Grain size determinations on gradesTP309H,TP309HCb,TP310H,TP310HCb,and UNSS32615shall be made on the same number of tubesas prescribed for theflattening test.10.Lengths10.1Pipe lengths shall be in accordance with the following regular practice:10.1.1Unless otherwise agreed upon,all sizes from NPS1⁄8to and including NPS8are available in a length upto24ft[Note4]with the permissible range of15to24ft [Note4].Short lengths are acceptable and the number and minimum length shall be agreed upon between the manu-facturer and the purchaser.NOTE4—This value(s)applies when the inch-pound designationof this specification is the basis of purchase.When the“M”designationof this specification is the basis of purchase,the corresponding metric value(s)shall be agreed upon between the manufacturer and the purchaser.10.1.2If definite cut lengths are desired,the lengths required shall be specified in the order.No pipe shallbe under the specified length and not more than1⁄4in. [6mm]over that specified.10.1.3No jointers are permitted unless otherwise specified.11.Workmanship,Finish,and Appearance11.1Thefinished pipes shall be reasonably straight and shall have a workmanlikefinish.Imperfections maybe removed by grinding,provided the wall thicknessesare not decreased to less than that permitted in Section8of Specification A530/A530M.12.Repair by Welding12.1For welded pipe whose diameter equals or exceeds NPS6,and whose nominal wall thickness equals or exceeds0.200,weld repairs made with the addition of compatiblefiller metal may be made tothe weld seam with the same procedures specified for plate defects in the section on Repair by Welding of Specification A530/A530M.12.2Weld repairs of the weld seam shall not exceed 20%of the seam length.48212.3Weld repairs shall be made only with the gas tungsten-arc welding process using the same classifica-tion of barefiller rod qualified to the most current AWS Specification A5.9as the grade of stainless steel pipe being repaired and as shown in Table4.12.4Pipes that have had weld seam repairs with filler metal shall be uniquely identified and shall be so stated and identified on the certificate of tests. 13.Certification13.1In addition to the information required by Specification A530/A530M,the certification shall state whether or not the material was hydrostatically tested.If the material was nondestructively tested,the certification shall so state and shall show which standard practice was followed and what reference discontinuities were used.14.Marking14.1In addition to the marking specified in Specifica-tion A530/A530M,the marking shall include the NPS(nominal pipe size)and schedule,heat numbering and NH when hydrotesting is not performed and ET when eddy-current testing is performed or UT when ultrasonic testing is performed.The marking shall also include the manufacturer’s private identifying mark,the marking requirement of9.4,if applicable,and whether seamless or welded.For Grades TP304H,TP316H, TP321H,TP347H,TP348H,and S30815,the marking shall also include the heat number and heat-treatment lot identification.If specified in the purchase order,the marking for pipe larger than NPS4shall include the weight.ernment Procurement15.1Scale Free Pipe for Government Procurement:15.1.1When specified in the contract or order, the following requirements shall be considered in the inquiry,contract or order,for agencies of the U.S. Government where scale free pipe or tube is required.

Arbitrary Function GeneratorsAFG31000 Series DatasheetThe Tektronix AFG31000 Series is a high-performance AFG with built-in arbitrary waveform generation, real-time waveform monitoring, and the largest touchscreen on the market. Providing advanced waveform generation and programming capabilities, waveform verification, and a modern touch-screen interface, the new AFG31000 is sure to delight and simplify the job of every researcher and engineer.Key performance specifications1 or2 channel modelsOutput amplitude range 1 mV P-P to 10 V P-Pinto 50 Ω loadsBasic (AFG) mode:25 MHz, 50 MHz, 100 MHz, 150 MHz, or 250 MHz sine waveforms250 MSa/s, 1 GSa/s or 2 GSa/s sample rates14-bit vertical resolutionBuilt-in waveforms include sine, square, ramp, pulse, noise, andother frequently used waveformsSweep, Burst, and Modulation modes (AM, FM, PM, FSK, andPWM)Advanced (Sequence) mode:Continuous mode (optional Sequence, Triggered and Gatedmodes)16 Mpts arbitrary waveform memory on each channel (128 Mptsoptional)Up to 256 steps in sequence mode with loop, jump and wait events Variable sampling clock 1 µSa/s to 2 GSa/sKey featuresPatented InstaView ™ technology enables engineers to see the actual waveform at the Device Under Test (DUT) in real time, without the need of an oscilloscope and probe, eliminating the uncertainty causedby mismatched impedanceSequencing option adds the ability to program long, complexwaveforms with up to 256 stepsThe 9-inch capacitive touch screen works like a smart phone and hasshort-cuts to frequently used settingsBuilt-in ArbBuilder lets you create and edit arbitrary waveforms on theinstrument, eliminating the need to connect to a PCOutputs are protected from over voltage and current to minimizepotential instrument damageCompatible with TekBench ™ software to help students set up, control,and analyze test results in the labApplicationsAdvanced researchClock and system synchronizationReplication of real world signalsComponent and circuit characterization and validationEmbedded circuit design and testGeneral purpose signal generationBasic and Advanced ModesThe AFG31000 series is the industry’s first arbitrary function generator with full function Basic (AFG) and Advanced (Sequence) modes.In Basic mode, the AFG31000 generates traditional functions and arbitrary waveforms. The touchscreen and front-panel controls make it simple to set up.Basic mode lets you change frequency without the need to worry about waveform length and sample rate. This feature is useful in analog designs that characterize filter/amplifier frequency responses or in digital designs where clock rates change frequently.Key settings are visible at a glance, and are easy to adjust using touch, numeric keypad, or rotary controlsNew with the AFG31000, Advanced mode provides the ability to generate multiple waveforms with complex timing. In this mode, you can compose a list (or a sequence) of 1 to 256 waveforms, with total waveform length up to 16 Mpts/ch (128 Mpts/ch optional) and define the ouput sequence of these waveforms. Repeat, go-to, wait, jump, and triggered events are all supported and the large memory provides space to store many waveforms or long waveforms.This feature is very useful in applications where many test cases need to be performed sequentially. Instead of loading the test cases one by one, you can put all of them in a sequence and load at one time, switching from one to another seamlessly to greatly improve the test efficiency.Advanced mode lets you build complex waveform sequences with flexible step controlsSequenced sine waveforms with different frequency and amplitude. Additionally, Advanced mode uses variable sample rate technology. Every sample in a waveform is output once and only once in each cycle, synchronized to the sample rate. Since there is no skipping or repetition, all details in the waveforms are kept. This feature is very useful for applications in which signal fidelity is extremely critical, such as IQ modulation and pulse train generation.InstaView™ technology shows the actual waveform at the DUTMost waveform generators assume they are driving a 50 Ω impedance. However, most devices under test do not have a 50 Ω impedance. This mismatch results in an inconsistency between the waveform as set on the AFG and the signal at the DUT.DatasheetWith InstaView turned off, the AFG31000 works like a traditional function generator. Due to an impedance mismatch, the AFG display shows a different waveform from the one observed at the DUT.With the patented InstaView ™technology, the AFG31000 Series can display the actual waveform at the DUT, instead of just the nominalwaveform as set on the AFG. The waveform displayed on the AFG instantly responds to changes in frequency, amplitude, waveform shape, andimpedance changes at the DUT. InstaView helps eliminate the uncertainty and measurement risk caused by impedance mismatches, without requiringadditional cables, instruments, or effort.With InstaView turned on, the AFG31000 shows the waveform as observed at the DUT.A large touch screen and smart user interfaceThe large 9-inch capacitive touch screen displays all related settings and parameters on a single screen. Similar to smart devices, you can tap or swipe to easily select, browse, locate and change settings and parameters.Frequently-used functions are immediately accessible. Familiar buttons and rotary knob controls are available for more traditional navigation.Frequently used settings are easy to access from the swipe-up menuAFG31000 SeriesBuilt-in ArbBuilder tool makes creating and editing arbitrary waveforms easier than ever In the past, you needed a PC with waveform editing software to create or edit your arbitrary waveforms. The waveform would then need to be downloaded to the AFG using either a USB stick or a data cable connection. The process was time-consuming, especially when waveforms required frequent changes.ArbBuilder is a built-in application on the AFG31000 series that lets you create and edit your arbitrary waveforms directly on the generator. You can create arbitrary waveforms with the Equation Editor tool or start from a library of standard templates. Thanks to the large capacitive touch screen, you can drag, pinch and zoom to get the detail you need.You can quickly replicate real-world waveforms captured with oscilloscopes or created by third-party software by loading CSV format data files directly into ArbBuilder from a USB memory stick.Creating an arbitrary waveform using the easy touch screen interfaceSimplified multi-unit synchronizationMost applications need one or two channels of output, but some applications require more channels. For example, in order to simulate 3-phase power signals, engineers often need to synchronize three 2-channel generators; one for the voltage and current on each phase. To do this used to be time-consuming, as it required many cable connections between the AFG units, and making changes in deep branches of the menu trees on all instruments.The AFG31000 simplifies this process with an onscreen wizard that leads you through the process of making cable connections and configuring settings to synchronize multiple generators.An on-screen wizard guides you through the process of multiple-unit synchronizationUpgradability protects your investmentThe AFG31000 provides upgrade options for bandwidth, memory extension, and sequence mode support. These options can be installed at the factory or at any time after purchase. This upgradability helps to reduce the product ownership threshold. And when your test requirements change, you can purchase and install upgrade software licenses to add higher performance features. Upgrades eliminate the concern about the return on investment during the instrument lifetime.DatasheetAFG31000 SeriesSpecificationsAll specifications are guaranteed unless noted otherwise.
