摘要:通过实地调研与会议座谈，对装配式混凝土结构的施工安全风险进行识别，并运用贝叶斯网络对其进行定量评价.研究结果发现，构件吊装时失稳发生的概率最高，其次是预制构件堆放时的倾倒，发生概率最低的是吊装时构件剧烈晃动.针对装配式混凝土的施工安全问题，分别从微观的施工现场、项目设计与施工协同角度和宏观产业发展环境角度提出具体的风险管控措施，构建了多角度、多阶段的施工风险综合防控机制，为装配式混凝土结构的施工安全管理提供了参考与借鉴.



Abstract:The safety risks of prefabricated concrete structure in the construction phase are identified through field research and conference discussion, and are quantitatively evaluated by using Bayesian network. The results show that the probability of prefabricated components instability during hoisting is the highest, followed by prefabricated components toppling, and the violent sloshing of prefabricated components during hoisting. To deal with these safety problems, concrete risk control measures are proposed from a microcosmic perspective of site management, design and construction coordination in project and a macrocosmic perspective of development environment in industry. A multi-angle and multi-stage construction risk prevention and control mechanism is constructed, which will provide reference for construction safety management of prefabricated concrete structure.
