Based on ISM—NK Tunnel Fire Multi-Factor Coupling Evolution Game Research

A tunnel is a complex network system with multiple risk factors interacting. At present, the cause analysis of fire accidents focuses on exploring sources and assessment, ignoring interaction between factors. single model has certain limitations. By proposing concept multi-factor coupled evolutionary game fire, integrating natural killing (NK) explanatory structure (ISM), coupling studied from perspective micro macro analysis, qualitative quantitative research, relationship effect are discussed, 100 158 literature at home abroad analyzed, 40 typical 31 types extracted. Using combined ISM-NK model, seven-level accident constructed, degree various evaluated. The hierarchical cascade revealed that 4 were underlying factors, 23 shallow layers direct influencing 13 middle-risk indirect NK shows increase nodes, frequency also an upward trend, subjective factor fires have higher than objective
