Study on Risk Assessment of Highway Tunnel Operational Safety
(1 Key Laboratory of Transportation Tunnel Engineering, Ministry of Education, School of Civil Engineering, Southwest Jiaotong University, Chengdu 610031;2 Sichuan Provincial Transportation Department Highway Planning, Survey, Design And Research Institute, Chengdu 610041)
Abstract According to the characteristics of highway tunnel accidents, the subject tunnel was divided into three research sections. A comprehensive analysis of the various factors affecting the operational safety of highway tunnels was carried out, a hierarchical structure model of the three sections was set up, and relative weights of the factors influencing the evaluated objects were obtained by an analytical model. Finally, a multi- hierarchy comprehensive evaluation on the three sections was carried out by the fuzzy logic comprehensive judgment method, and a scientific and reasonable method for highway tunnel operational security risk assessment was developed.
