资料简介： 摘 要 本次设计是一级公路第十五标段的设计。公路全长2995m，设计车速为80km/h，双向四车道，设置中央分隔带。
设计中主要包括以下几个阶段：
（1）主线平面设计：全线长2995米，在这段路上选了三个交点，交点半径均为400m。
（2）纵断面设计：考虑满足排水的最小纵坡要求进行了路线纵断面设计。全线共有两个变坡点，半径均为10000m。
（3）横断面设计：以桩号为基本点，进行了横断面设计、路基设计表设计、土石方计算、排水平面设计等。
（4）路面结构设计：采用手工和程序相结合的办法进行了路面结构设计。
（5）预算：编制了路线范围内路基和路面部分的预算文件。
大部分图纸使用CAD绘制，部分数据使用EXCEL计算。
关键词： 主线平面设计、纵断面、横断面、路面结构设计
Abstract
This design is Huaxian to Changyuan fifteenth Sections of arterial road design. the length of this road which we design is 2995m, the speed is 80km/h, two-way four-lane andset up the central of separation strip.
（1）Master line plane design: 2.995km long line in this election, three points on the road, intersection radius of 400m
（2）Longitudinal section design: Considered that satisfied draining water the smallest lengthwise grade request to carry on the route longitudinal section design. The entire line altogether has three changes the slope spot, Radius of 10000m;
（3）Cross section design: Take the station number as the fundamental point, has carried on the cross section design, the grade location table design, the cubic meter of earth and stone computation, the draining water plane design and so on.
（4）Pavement structure design: Uses the means which the handwork and the procedure unify to carry on the pavement structure design.
（5）Budget: Has established in the hole scope the roadbed and the road surface part budget document.
The majority of blueprints use the CAD plan, the partial data use EXCEL to calculate.
Key word: Master line plane design, longitudinal section, cross section, pavement structure design
