摘　　要：双车道公路由于建设投资、地形地貌等诸多因素限制,在进行公路线形设计时常采用规范规定的极限指标,存在一定的安全隐患,实际运营中交通事故率较高。文章以模糊数学理论为指导,建立双车道公路的几何线形安全评价体系,确定安全评价打分标准,建立相关隶属函数,对各安全评价指标赋权,最终评价双车道公路整体线形的安全等级以提出针对性的工程改善对策。Due to limits of the investment,terrain and many other restrictions,limit indicators are often used in the double-lane highway alignment design,which causes more safety problems and higher accident rates.Based on Fuzzy theory,a alignment safety evaluation system for double-lane highway is established to determine the scoring criteria,the membership function of each index empowerment is established,the final evaluation of the safety level of the overall alignment is got,evaluation results could be taken as reference for engineering improvement.

关 键 词：双车道公路 模糊理论 线形设计 安全评价
