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,公路设计使用年限为15年。该路线总长为13156.15m,共设6个平曲线,具体平曲
2、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)AbstractThedesignisentitled:HuludaoWanjiaseasideroad,whichisinLiaoningprovince,anditgra
