In response to the problem of multiple factors affecting construction risks and long impact periods during the construction of mountain tunnels,in order to reduce the occurrence of collapse and water inrush accidents during tunnel construction,based on the characteristics of risk factors affecting mountain tunnel construction,and relying on the Wenbishan No.1 tunnel on Puyan expressway,the fuzzy analytic hierarchy process with iterative confirmation is used to determine and rank the construction risk factor weights of tunnel collapse and water burst.Combined with the established mountain tunnel construction risk consequence assessment model,a model that can quickly,simply and accurately evaluate the construction risk degree of mountain tunnel collapse and water burst is proposed.The results indicate that the risk assessment result of the risk grade is in good agreement with the actual situation.It is verified that the construction risk assessment system for water burst and collapse in mountain tunnels is scientific and effective.In addition,the findings are reference to similar tunnel construction projects.
