【摘要】 为降低火灾后建筑结构加固施工过程中事故的发生率,保障加固施工作业过程的安全,针对我国建筑火灾后加固施工项目的特点,构建了多因素耦合作用下的基于熵权-未确知测度理论的建筑火灾后加固施工过程风险性评估模型,并将模型应用于五个工程实例中,取得了良好的效果。研究结果表明,该模型是熵权理论、未确知测度理论的的有机结合,为定量研究建筑火灾后加固施工过程安全风险,并有效的控制安全风险,确保施工安全提供了新的思路。更多还原

【Abstract】 In order to reduce the occurrence of safety accidents in reinforcement construction process of post- fire building structure and ensure the safety of working process,aiming at the characteristics of the reinforcement construction projects of post- fire buildings in China,a risk assessment model on reinforcement construction process of post- fire building based on the entropy weight- uncertainty measurement theory by multiple- factor coupling was established,then the model was applied in five engineering cases,and the good results were obtained. It showed that the model is an organic combination of the entropy weight theory and the uncertainty measurement theory,and it provides a new idea for the quantitative study on the safety risk in the construction process of post- fire building and the effective control of safety risk,so as to ensure the construction safety.更多还原
