Abstract

In order to reduce the incidence of accidents in bridge detection operation and make up for defects such as single assessment means, backward management methods in operation at present in China, the risk assessment index system with five first-level indexes and 24 second-level indexes was constructed from five dimensions of human, machine, material, environment and management on the basis of accident cause theory. Based on matter-element extension theory, the risk assessment model of bridge detection operation was established, and correlation function of each assessment index was calculated. The weight of index was determined by entropy weight method, and risk assessment grade was obtained. And then 14 engineering examples were selected to verify the model. The results show that risk assessment results of 14 bridge detection projects are consistent with the on-site field survey results, indicating that the proposed risk assessment model of bridge inspection operation based on entropy weight method and matter-element extension theory has high reliability and accuracy. © 2019 China Safety Science Journal
