基于WSR的装配式预制构件吊装施工安全评价分析

Safety Evaluation and Analysis of Prefabricated Component Hoisting Construction Based on WSR

为准确评估装配式建筑预制构件吊装施工的安全状态,文章在多因素耦合视角下构建预制构件吊装施工安全事故致因模型。首先基于施工单位责任视角,采用WSR方法论从“物理-事理-人理”三个层面识别并筛选出预制构件吊装施工安全风险的影响因素;其次利用C-OWA算子构建改进相互作用矩阵,并进行风险耦合分析;最后结合实例验证该方法的实用性。结果表明,项目整体风险等级偏高。项目管理者应采取有效的防御措施,控制施工过程中的高权重风险因素,降低安全事故发生的概率。

In order to accurately evaluate the safety status of prefabricated building components hoisting construction,this paper constructs the cause model of prefabricated components hoisting construction safety accidents from the perspective of multi factor coupling.Firstly,based on the perspective of the responsibility of the construction unit,the influencing factors of the safety risk of prefabricated component hoisting construction are identified and screened from the three levels of"physics,reason and human reason"by using WSR methodology;Secondly,the improved interaction matrix is constructed by using C-OWA operator,and the risk coupling analysis is carried out;Finally,the practicability of the method is verified by an example.The results show that the overall risk level of the project is relatively high.Project manager should take effective defense measures to control high weight risk factors in the construction process,the probability of safety accidents can be reduced.
