摘要
本设计根据给定的资料，通过对原始数据的分析,根据该路段的地质、地形、地物、水文等自然条件,依据《公路工程技术标准》、《公路路线设计规范》等交通部颁发的相关技术指标,在老师的指导和同学的帮助下完成的。
设计内业详细资料有：路线设计，包括纸上定线（山岭区或越岭线）、绘制路线平面图、路线纵断面设计）；路基设计，完成两公里横断面和路基土石方的计算及路基排水设计；路面设计，水泥混凝土路面设计；小桥涵设计，完成一项涵洞设计；路线交叉设计，完成一项路线平面交叉；设计概算编制，完成全线设计路段的初步设计概算；应用计算机绘制工程图，按老师指导和要求完成。
整个设计计算了路线的平、纵、横要素,设计了路基、路面、平面交叉、小桥涵的尺寸等内容,由此圆满完成了北翠公路青年农场至前进段两阶段初步设计。
关键词：路线，路基,路面,涵洞，平面交叉，概算
ABSTRACT
Data that this design according to give to settle to complition, complete the Threexin forest of Mulin to lianhe highway station segment (1) first design station segment (2) the relevant technique index sign for kind, geography for second class highway route, from this design learning a lot of knowledge concerning highways, passing analysis primitive dataing, according to the road's segment, characteristics of term nature, such as, ground thing, and hydrology etc., Basis highway engineering technique standard,highway route designing the normal waiting the transport, and complete to design under the help that the teacher's leading is with the classmate of constitute the circumstance,
The design inside of stage first steps include: Route design,The paper up settles the lines( mountain range area, or more mountain range line),Draw the route plane chart, Proceed route vertical section of design;Roadbed design, Complete two kilometer cross sections are with the roadbed the calculation of square ground and roadbed drain the design;Road design, Cement concrete road design;Small bridge culvert design, Complete the design of a culvert;The route crosses the design, Complete a route flat surface to cross; Design budgetary estimate establishment: Completes the entire line todesign the road section the preliminary design budgetary estimate;The application calculator draws the engineering diagram, Complete under the teacher's leading request.
we compute the route even, vertical , horizontal main factor, designed the flat surface to designtheroadbed,roadthesizefor, small bridge culvert, fromhere,successfully completed Qingnian to Qianjin of the Beicui highway in section two stages preliminary designs.
Key words: Route, roadbed, road, culvert，Route cross，Budgetary estimate
