山区公路桥隧结合段风险影响因素分析

Analysis on Risk Factors at Bridge and Tunnel Connecting Segment in Mountainous Areas

文章通过选取山区高速公路桥隧结合段行车安全风险影响因素及建立评价递阶层次结构模型,利用层次分析法对各风险影响因素进行了定量化分析,确定了各各风险影响因素的权重,为山区公路桥隧及桥路结合段的行车安全性评价提供参考。

Through selecting the risk factors that affect the traffic safety at bridge and tunnel connecting segment of roads in mountainous areas and building hierarchical structure evaluation model,the article uses analytic hierarchy process to perform quantify analysis on different risk factors and determines their weights,which provides reference to assess the traffic safety.
