1、双向两车道的三级公路设计毕业论文设计计算书(此文档为word格式，下载后您可任意编辑修改！)摘要本次毕业设计为（A）标段，自东南向东北略呈倾斜。中部为山岭区和农作区交替变化。主要进行公路线形、路基和路面设计。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、路基边坡设计等；路面设计包括路面结构层设计、路面结构层厚度设计和路面结构层验算。确定道路的等级以及道路设计的各个技术指标，为公路路线方案的比选准备了原始材料，确定了线路的平面位置。并且本设计对方案进一步细化，对路线的平面和纵断

2、面进行了综合分析，根据技术标准及当地实际情况确定了路基宽度、高度及边坡坡度并且对路面材料、横断面布置、曲线超高及加宽的设置做了精心设计。关键词:线形；缓和曲线；竖曲线；路基；路面Thisgraduationdesignisa(A)section,fromthesoutheasttotheNortheastslightlyinclined.Centraltothemountainareaandfarmingregionalternation.Themain.Amongthem,thealignmentdesig
