1、 1 / 83 摘摘 要要 根据设计任务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 怀化至通道高速公路 K176+500-K178+500 段提供了路基路面综合设计。 此次设计主要内容包括：路线设计、路基、路面设计，英文翻译，计算机程序 编制。根据提供的路线原始资料，考虑土石方填挖平衡、最大纵坡、最小纵坡、坡 长、高程控制点等因素进行纵断面设计,由此结合平面图进行横断面设计。根据设计 段内的地形状况，设置了边沟、截水沟、排水沟、圆管涵等排水设施。同时，进行 挡土墙设计计算和防护工程设计,设置挡土墙，采用植草皮等形式进行边坡防护。高 填路堤路段采用修筑挡土墙的方法收缩坡脚，减少填方，
2、增加路堤边坡稳定性；用 毕肖普法进行了边坡稳定性验算。设计进行了沥青混凝土路面的设计和水泥混凝土 路面的设计，由给定的交通量等条件，按照路面结构组合设计的原则，选用不同路 面结构层厚度和材料进行结构设计验算。 通过本次毕业设计，在专业知识方面得到了综合训练和提高，增强了独立分析 问题和解决问题的能力。 关键词：高速公路、路基设计、路面设计、综合设计 ABSTRACT 2 / 83 According to the design information, demands of the design task instrument, the technical standards and spec
3、ifications for highway design published by the Ministry of Communications of China, the comprehensive design of highway subgrade and pavement from K178+500 to K178+500 has been carried out based on the data of HuaihuaTongdao expressway in HuNan province. Our prime contents of the design project incl
4、udes highway vertical alignment, the design of pavement, translating an English article into Chinese, and compile a simple computer programme. According to route firsthand information that is offered ,we must onsider the balance between the diging of filling out,heavy vertical slope, minimum vertica
5、l slope, the longth of slope, high control point,etc. During designing the vertical section, and combine the plane figure and design the cross section. According to the condition of climate district and remitting calculation water of quantity, set up side ditch, intercepting ditch, round culverts, c
6、over pulls culverts etc. Meanwhile, do block design of wall of soil calculate and protect engineering design , set up the retaining wall to go on, adopt plant turf to protect the slope ,etc. In high embankment highway section, shrink slope foot by building the retaining wall, reduce the filling, increase the slope stability; make use of BISHOP to follow the checking stability calculation. Do the design which has carried on the pitch concrete road surface and design
