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。
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 .
