| 摘 要： | 山区双车道公路由于地形、环境以及投资等具体条件限制,在线形设计时采用较多极限指标,不利于行车安全。采用模糊数学理论,建立线形安全评价体系,确定评分标准、建立隶属函数,对各指标赋权,最终评价整体线形的安全等级,遴选出不安全路段,提出针对性的改善对策以提高整体安全水平。

| Abstract: | Due to restrict of the terrain,environment and investment and other specific conditions,more extreme indexes adopted in the alignment design of Mountainous two-lane highways,so it goes against driving safety.Based on the Fuzzy mathematics theory,the paper built an alignment design safety evaluation system to determine the score,set up membership function of the index weight to finally evaluate the overall alignment of the safety level and to select the unsafe sections,and then put forward improvement strate... |
