1、 I 摘 要 在本设计中，主要是进行东深高速公路的设计。设计部分的公路全长 2534m， 设计车速 120km/h，双向四车道，设置中央分隔带。 对交通量进行了分析，查找相应技术规范，确定公路的等级以及设计需要的 各种参数。在平面图中进行选线，然后又对道路路线进行了平面线形设计，本路 线有两段曲线设置缓和曲线，并设置超高。纵断面的设计中有三个竖曲线，并且 也满足了平纵面线形组合设计中的各种要求。在横断面的设计中，确定了横断面 组成及各种要素后，绘制横断面图。路基设计的基本内容，就是确定路基边坡的 形状和坡度。在挡土墙设计中满足了各种稳定性的验算。路面设计内容中包括路 面类型与结构设计。最后的概
2、算设计为计算机辅助计算，同时也给出了各部分内 容相关的表格与图纸。 通过这次设计不但了解建设公路的各个步骤，而且也能熟练的运用 AUTOCAD 进行制图。 关键词 高速公路 线形设计 路面 路基 挡土墙 II Abstract In this design， is mainly the dongshen expressway design， the length of this road which we design is2534m， the design of the speed is 120km/h and set up the central of separation strip.
3、Has carried on the analysis to the volume of traffic， search corresponding technical specifications， highway to determine the levels of need and the design of the parameters . Carries on the route selection in the horizontal plan， then carried on the plane geometric design to the path route. This ro
4、ute has two sections of curves establishments transition curve and super elevation. There are three vertical curves in this Profile Design. And also meet various requirements of vertical surface linear combination design.Has determined the cross section composition and various elements in Cross section design and draws up the cross section chart. The roadbed design of basic content is determining roadbed side slope form and slope. In the design of retaining walls is to meet a variety of recalcul
