装配式建筑施工安全风险评价研究--基于G1-熵权法及未确知测度模型

Construction Safety Risk Assessment of Prefabricated Building:Based on G1-Entropy Weight Method and Uncertainty Measure Model

为在装配式建筑施工过程中预防安全事故,有效地实现安全风险把控,进行科学的安全评价,采取G1-熵权法得到了综合指标权重,运用未确知测度模型对装配式建筑施工安全风险进行了分析,依照置信度识别准则判断其风险等级,并取实际工程进行案例分析,得到了良好评价的结果,为装配式建筑施工安全管理提供了借鉴与参考。

In order to prevent safety accidents in the process of assembly building construction,effectively control safety risks and carry out scientific safety evaluation,the comprehensive index weight is obtained by adopting G1-entropy weight method.The uncertainty measure model is used to analyze the safety risk of prefabricated building construction and the risk level is judged according to the confidence recognition criterion.Combined with the analysis of engineering cases,a good evaluation result has been obtained,which provides reference for the safety management of prefabricated building construction.
