摘　　要：为了提高装配式建筑施工安全风险管理水平,在传统4M1E分析基础上,提出5M1E构建装配式建筑施工安全风险的评价指标体系。采用二项式系数法客观赋权并引入熵权理论进行指标权重的修正。提出建立物元评价模型用以评价装配式建筑施工安全风险等级。结果表明:S30集体宿舍楼工程施工安全风险等级为Ⅱ级,属于较低风险;其中人员、方法、材料风险等级为Ⅲ级,机械、环境、管理风险等级为Ⅱ级。该方法具有较好的可靠性和可操作性,为装配式建筑施工安全管理提供借鉴参考。In order to improve the safety risk management level of prefabricated building construction,an evaluation index system of 5M1E assembly construction safety risk is proposed based on the traditional 4M1E analysis.The binomial coefficient method is used to objectively weight and introduce the entropy weight theory to correct the index weights.It is proposed to establish a matter-element evaluation model to evaluate the safety risk level of prefabricated building construction.The results show that the safety risk level of the construction for S30 collective dormitory building is Grade II,the personnel,method and material risk level is Grade III,and the mechanical,environmental and management risk levels are Grade II.The method has good reliability and operability,and can provide a reference for the safety management of fabricated building construction.
