文档介绍：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3500m,设计车速100km/h,双向六车道,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。纵断面的设计中有五个竖曲线,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
Abstract
In this design, is mainly the dongshen expressway design, the length of this road which we design is 3500m, the design of the speed is 100km/h and set up the central of separation strip.
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 route has two sections of curves establishments transition curve and super elevation. There are five vertical curves in this Profile Design. And also meet various requirements of vertical surface bination determined the cross position 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 recalculations Stability. Pavement Design elements include road type and structure design. Final budgetary is estimate design puter putation, also discussed some of the content of the forms and drawings.
This design not only to understand the various road-building steps, but also skilled in the use of AutoCAD
Keywords expressway alignment design road surface roadbed retaining wall
