ABSTRACT

In order to make the risk assessment of highway tunnel collapse more scientific and reduce the risk of collapse accidents during tunnel construction, this paper proposed a collapse risk assessment model for highway tunnel construction based on game theory and the mutation progression method. Firstly, an index system of highway tunnel construction collapse risk assessment was established, and then a comprehensive weighting of the indexes was determined based on the entropy and CRITIC methods, combined with game theory ideas, and finally, the mutation level method was applied to the risk assessment. The model was compared with the results of the survey and the fuzzy hierarchical analysis. The results show that the model is more consistent with the actual situation and can provide a reference for the risk assessment of highway tunnel construction collapse, so as to effectively reduce the occurrence of tunnel collapse accidents.
