湖南省永州至蓝山高速公路路基路面综合设计
K70+200~K72+300
摘要
根据设计任务书和指导书提供的设计资料和设计要求以及交通部颁发的标准和规范对湖南永州至蓝山高速公路70+200-K72+300段进行了路基路面综合设计.该路段全长2.1公里,设计车速100km/h,路基宽度为26m。

此次毕业设计主要包括的内容如下:
1、路线设计:根据已有的资料,考虑土石方填挖平衡、经济合理、最大纵坡、最小纵坡、坡长、高程控制点等进行纵断面的设计,并结合平面图进行横断面设计。

2、路基设计:包括填挖较大路段利用bishop法进行边坡的稳定分析、整个线路的土石调运借配等。

3、支挡工程:挡土墙的计算。

4、防护工程:采用草皮防护、骨架防护和护面墙等防护形式。

5、路面设计:路基在不同干湿状态下,所设计的沥青路面和水泥混凝土路面方案的比选。

6、路基、路面排水工程;根据设计段内的地形状况,设置了边沟、截水沟、排水沟、急流槽、圆管涵、盖扳涵、通道等排水设施。

7、英文翻译。

8、计算机程序编制。

THE COMPREHENSIVE DESIGN OF SUBGRADE AND PAVEMENT FROM K70+200 TO K72+300 OF YONGZHOU-LANSHAN EXPRESSWAY IN HUNAN
PROVINCE
ABSTRACT
According to the design information,demands of the design task instrument,the technical standards and specifications for expressway design published by the Ministry of Communications of China,the comprehensive design of expressway subgrade and pavement from
K70+200 to K72+300 has been carried out based on the data of Yong—
lan expressway in HuNan province. The design length is 2.1 km,which speed is 100km/h and the wide of the subgrade is 26m.
The prime contents of the design project includes:
(1)expressway alignment :According to route firsthand information
that is offered ,we must consider the balance between the diging of filling out,heavy vertical slope,minimum vertical slope, the longth of slope,high control point,etc.
(2)The design of the subgrade, and the work involves a lot of items:
analyze the stability of brae using bishop; the fill or dig
height of every peg and so on.
(3)Repaining works:retaining wall calculation.
(4)Protection engneering:dopt plant turf to protect the slope ,etc.
(5)The design of pavement, and this contents that the select of the construction about concrete and asphalt pavement in different case.
(6)The design of the drainage project, Considering to the condition
of climate district and remiting calculation water of quantity,set up side ditch, intercepting ditch,escape canal, round culverts,
cover pulls culverts etc.
(7)Translate an English article into Chinese.
(8)Compile a simple computer programme.
Key words: expressway; route design; subgrade design; pavement design; drainage design。
