【Abstract】 In response to the frequent highway meteorological disasters and to make good decisions,the comprehensive evaluation index system for the resistant ability against disasters of highway network was constructed using the AHP and fuzzy mathematics theory,the specific evaluation method and procedure were detailed,the analysis method of the evaluation conclusion and the feedback method using reverse analysis were explored,and finally the evaluation method has been applied taking Hangzhou trunk highway network as an example.Practice shows that the conclusion of the evaluation for the highway network resistant ability against disasters was close to the actual situation and the method is feasible,furthermore the feedback study which could identify weaknesses in disaster and proceeding to put forward proposals is positive to improve the resistant ability against disasters of highway network.更多还原
