摘 要

本次毕业设计为肖家坝至跃进桥二级公路A标段，位于四川盆地北部低山丘陵区。主要进行公路线形和路基设计。其中，线形设计包括选线、方案比选、平面设计和纵断面设计；路基设计包括横断面设计、路基边坡设计。

平、纵、横设计使用AutoCAD2008、纬地5.88 计算机软件辅助设计，设计结果均符合相关规范和标准要求，使用AutoCAD2008 进行绘图，设计过程中的主要计算参数成果由WPS表格计算所得。

Abstract

The graduation design for Xiangjiaba to Yuejin bridge secondary highway (A) section, Locating in nortn of Sichuan. Then,alignment design included line and roadbed,project to compare to choose, the flat surface design and vertical section design.The roadbed design includes the cross section design and the roadbed side slope design and so on.

The evaluation results showed that the designed line had good design quality. AutoCAD2008, Weft 5.88 have been used in the design of Planar graph, profile and cross section.Design results conformed to the requirements of the relevant norms and standards. AutoCAD2008 was been used in drawing,Main calculation parameters in the design were processed by WPS Excel .

Keywords:　 secondary road；vertical curve ; road bed ;Weft；AutoCAD2008
