摘　　要：引入可拓云理论构建了化工建筑施工安全风险评估模型,在该模型内,最优最劣法和CRITIC法分别用于计算主客观权重值。研究应用博弈论确定组合赋权权重值,以消除主客观权重法之间的误差。最后,计算可拓云模型内模糊等级特征期望值Erq、模糊等级特征熵值Ers、综合评判向量B和置信度因子g等参数。结果表明:该化工项目施工安全综合风险等级为中等,模糊等级特征期望值Erq为2.952 8,模糊等级特征熵值Ers为0.016 5,置信度因子g为0.005 6,符合一致性要求,结果可信。研究结果为现场安全管理人员提供参考。This paper introduces the theory of topological clouds to construct a chemical building construction safety risk assessment model.In this model,the optimal worst method and the CRITIC method were used to calculate the subjective and objective weight values respectively.This paper studies the application of game theory to determine the weight value of combination weighting to eliminate the error between subjective and objective weight methods.Finally,the parameters such as the expected value of fuzzy grade feature Erq,the entropy value of fuzzy grade feature Ers,the comprehensive evaluation vector B and the confidence factor g in the extension cloud model were calculated.The results show that the comprehensive risk level of construction safety of the chemical project is medium.The expected value Erq of fuzzy grade characteristic is 2.9528.The entropy value Ers of fuzzy grade characteristic is 0.0165.The confidence factor g is 0.0056,which meets the consistency requirements,and the results are credible.The research results provide reference for on-site safety management personnel.
