[Abstract]:Because of the complexity and uncertainty of risk, risk control is the key to tunnel construction safety. The evaluation index system of highway tunnel construction risk and its evaluation standard are established, and the weight solving model of tunnel risk evaluation index is established by using fuzzy analytic hierarchy process (FAHP) theory. Combined with the improved set pair analysis method (ISPA), the risk evaluation model of highway tunnel construction is established, and the semi-quantitative evaluation of tunnel construction risk is realized. The concepts of partial connection number (PCN) and set pair potential (shi) of multivariate connection number are introduced. The dynamic evaluation model of tunnel construction risk is established with FAHP-ISPA-PCN coupling. The FAHP-ISPA-PCN model realizes the situation analysis and development trend analysis of the two-level risk evaluation index model of tunnel and improves the risk assessment of tunnel construction.
