2、g Institute of Technology2009-06HarBin摘 要本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。山区公路选线即要考虑行车的安全、线形的美观、与环境相协调又要考虑其经济性。设计内业详细资料有：路线设计，包括纸上定线（山岭区或越岭线）、绘制路线平面图、路线纵断面设计）；路基设计，完成两公里横断面和路基土石方的计算及路基排水设计；路面设计，水泥混凝土路面设计；小桥涵设计，完成一项涵洞设计；路线交叉设计，完成一项路线平面交叉；
3、设计概算编制，完成全线设计路段的初步设计概算；应用计算机绘制工程图，按老师指导和要求完成。整个设计计算了路线的平、纵、横要素,设计了路基、路面、平面交叉、小桥涵的尺寸等内容,由此圆满完成了黑嫩公路曙光至安溪段两阶段初步设计。关键词：路线;路基;路面;涵洞;平面交叉;概算ABSTRACTData that this design according to give to settle to complition, complete the Threexin forest of Mulin to lianhe highway station segment (1) first design sta
