Comprehensive Evaluation of Expressway Tunnel Safety

According to the overall detected results of an expressway tunnel,a linear substitution relationship between the safety situation of tunnel components and the overall estimated results is deduced via the multi-grade fuzzy comprehensive evaluation method,which is then used to evaluate the safety of the expressway tunnel.Practical application of the proposed method indicates that the method can objectively evaluate the safety of tunnel with quantified results.The research may provide some references for similar projects.
