ABSTRACT
In recent years, urban viaduct collapse accidents have occurred from time to time, which not only caused serious economic losses and casualties but also had a huge social impact. Based on the analysis of literature and cases, this paper firstly constructs an index system of influencing factors of urban viaduct collapse accidents, and then uses the DEMATEL method to analyze the influencing factors, and calculates the degree of influence, degree of influence, centrality, and cause of each influencing factor. The key influencing factors were found, and corresponding countermeasures and suggestions were put forward in a targeted manner.
