摘要

本设计是从到襄阳的某段高速公路的设计，该段路线总长为3050m。本设计中设计车速为120km/h，双向八车道,路基宽度为45m，设置中央分隔带，行车道宽3.75m，硬路肩3m，土路肩0.75m。

在平面设计中，通过方案比选确定最终线路，此线路中有三个平曲线。纵断面设计，主要包括三个竖曲线的设计。横断面设计中，确定路面横断面的形式，土石方的数量的计算和调配。在路基设计中，主要是确定路基的横断面形式和边坡的形式。路面设计中，确定了路面的结构层次。专题设计的主要容包括对盖板、基础、台身和洞口建筑的设计。最后利用工程造价软件得出对比方案和选定方案的工程预算。

ABSTRACT

This design is the design of a section of a highway from Xinyang to Xiangyang.The sec- tion of route is 3050m.In this design,the speed of design is 120km/h,two-way eight lane,subg- gade width of 45m,setting up the central separtion belt,lane width

3.75m,hard shoulder 3m, soil shoulder 0.75m.

In the graphic design,there are three horizontal curve in this line,determined by the sche- me xxparison.Longitudinal section design,design mainly includes three vertical curve.The cross-section design,determine the road cross section form,calculation and allocation of earth- work quantity.In the design of roadbed,mainly determine the embankment cross-section and the form of the slope form.The design of pavement structure,pavement was determined.The main contents of design project include the design of the cover,foudation,abutment and the building.Finally draw project budget of the xxparison scheme using the engineering cost project software.

Keywords:highway design;roadbed design;pavement design;culverts;project budget
