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.
