1、本科生毕业设计（论文）摘要本设计的题目是：辽宁葫芦岛绥中万家道路工程，路线属于公路自然区划II2a区。本次设计所采用的路线，是通过综合考虑交通量及其年增长率、地形与地貌、气候条件，施工条件等方面的因素后，进行方案比选采用最优方案。综合该地区的经济发展前景和交通量发展需求，从远景和近期的交通状况出发，确定采用高速路的技术指标进行设计，设计所采用的设计车速为：平原区80㎞/h，双向二车道，车道宽7.5m，路基宽12m，硬路肩1.5m，路缘带0.75m。根据交通量确定公路等级为二级公路，公路设计使用年限
2、为15年。该路线总长为13156.15m，共设6个平曲线，具体平曲线要素见后表，平曲线设置超高缓和段；竖曲线12个。路面设计为高级路面，路面采用沥青混凝土路面，本设计沥青路面设计理论以弹性层状体系理论为基础。为保证路基路面的强度和稳定性，延长道路的使用寿命，在做好路基路面设计的同时，还应对道路的排水进行设计。路基排水设计要因地制宜，全面规划，充分利用有利地形。关键词：交通量；平曲线；曲线超高；竖曲线；路基；沥青混凝土路面；桥；排水。V本科生毕业设计（论文）AbstractThedesignisen
