基于结构熵权-可信性测度理论的装配式建筑吊装施工安全风险评估

Safety risk assessment of prefabricated building hoisting construction based on structure entropy weight-credibility measure theory

为保证装配式建筑吊装施工安全,围绕吊装施工安全风险评估指标和模型展开了研究。针对我国当前装配式建筑吊装施工特点、常见安全事故类型及诱因,结合实地调研及专家咨询,构建了基于结构熵权-可信性测度理论的装配式建筑吊装施工安全风险评估模型,并将该模型应用到10个工程实例中,取得了良好的效果。结果表明,该模型是结构熵权与可信性测度理论的有机结合,为客观评估并有效控制装配式建筑吊装施工安全风险提供了新的思路。

To ensure the safety of prefabricated building hoisting construction, the research is carried out around the safety risk assessment indicators and models of hoisting construction. In view of the characteristics, the types and causes for safety accidents of the current prefabricated building hoisting construction in China, the risk assessment model of prefabricated building hoisting construction based on structure entropy weight-credibility measure theory is established through combining field research and expert consultation. The model is applied in ten projects, and good results are obtained. It is showed that the model is an organic combination of the structure entropy weight method and the credibility measure theory, and it provides a new idea for objective assessment and effective control of safety risks in prefabricated building hoisting construction.
