1、摘要为了巩固我们所学的知识，并在各方面得到更进一步的提高，我们选择了敦煌至当金山口新建二级公路的一段里程设计作为毕业设计，这是在毕业之前对自身学习状况的最后一次检查。我所选择的设计路段是从DK64+000至DK72+000.000,全长8000.000米，设计车速60km/h,路基宽度为10m。设计根据给定的资料，通过对原始数据的分析,根据该路段的地质、地形、地物、水文等自然条件，依据《公路工程技术标准》、《公路路线设计规范》等交通部颁发的相关技术指标，在老师的指导和同学的帮助下完成的。设计中主要运用了纬地软件，进行了平面设计（包括纸上定线（山岭区或越岭线）；平面分图；输出平面直曲表）、
2、纵断面设计（内容包括作出纵断面的拉坡图；纵断面图；输出路基设计表；路面加宽表；逐桩坐标表；竖曲线表）、横断面设计（内容包括横断面图的输岀；路基超高加宽表；土石方计算表）、关于公路桥涵的设计、公路隧道的设计，由此圆满完成了敦当二级公路的初步设计。关键词:平面设计纵断面设计横断面设计AbstractThedesignisveryimportanttous.Notonlybecausethisisourlastassignmentbeforegraduation,butalsoitcanenhanceourability.Inthisdesign,ourtaskistodesignanseco
