基于未确知测度理论的装配式建筑全过程安全韧性评估

The whole process safety resilience assessment of prefabricated buildings based on uncertainty measure theory

为保障装配式建筑全过程的安全性,有效减低事故发生率,将韧性理论引入装配式建筑安全管理中。对装配式建筑从决策到施工各阶段的安全管控机理进行了研究,并从各构成要素及要素间的联系考虑,建立了装配式建筑全过程安全韧性评估指标体系;采用未确知测度理论,构建了基于未确知测度理论的装配式建筑全过程安全韧性评估模型,并将该模型引用到具体的3个工程案例中,确定其韧性等级并排序。研究结果表明:该评估模型实用性较强,评估结果与客观实际相符,为装配式建筑安全管理提供了新的思路。

In order to ensure the safety of the whole process of prefabricated buildings and effectively reduce the accident rate,this paper introduces the resilience theory into the safety management of prefabricated buildings.It studies the safety management and control mechanism of prefabricated buildings from decision-making to construction,and establishes the evaluation index system of safety resilience of the whole process of prefabricated buildings,considering the dimension of each constituent element and the dimension of the connection among elements.Based on the uncertainty measure theory,this paper constructs the whole process safety resilience evaluation model of prefabricated buildings,and applies the model to three specific engineering cases to determine the resilience level and rank.The results show that the model has strong practicability,and the evaluation results are consistent with the objective reality,which provides a new idea for the safety management of prefabricated buildings.
