摘要/Abstract

摘要： 为弥补现阶段我国桥梁检测作业评价手段单一、管理办法落后等缺陷,降低桥梁检测作业安全事故的发生率,以耦合事故致因理论为基础,从人、机、料、环和管理等5个维度出发,构建包含5个一级指标,24个二级指标的桥梁检测作业危险性评价指标体系;结合物元可拓理论建立桥梁检测作业危险性评价模型,计算出各评价指标的关联函数,应用熵权法确定指标权重,得出危险性评价等级,并选取14个工程实例加以验证。结果表明:就14个桥梁检测工程实例的危险性而言,该模型评估结果与现场实际踏勘结果一致,说明基于熵权法与物元可拓理论相结合得到的桥梁检测作业危险性评价模型整体可靠性强、准确率高。

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.

Key words: bridge detection, multi-factor coupling, entropy weight, matter-element extension, risk assessment
