摘　　要：为提高装配式建筑吊装施工安全水平,准确判断吊装施工安全风险等级及等级趋势,构建了改进的变权物元可拓模型。在事故致因理论基础上从“人、物、技术、管理、环境”5个方面构建吊装施工安全风险评价指标体系;利用变权理论确定风险指标权重,改进物元可拓模型对吊装施工进行安全风险评价,将贴近度原则与物元可拓模型相结合确定风险等级,解决了以往无法反映装配式建筑吊装施工安全对风险等级界限的模糊性问题。以青岛某装配式建筑项目为例对模型进行了验证,结果表明:该项目吊装作业安全风险等级为较低风险,但略有偏向于中等风险的趋势,与传统风险等级评估方法对比,风险评估结果一致,验证了模型的可行性。In order to improve the safety level of hoisting construction of prefabricated buildings,and accurately judge the safety risk level and level trend of hoisting construction safety risk,an improved matter-element extension model with variable weight is constructed.Based on accident cause theory,the safety risk evaluation index system of hoisting construction is constructed from five aspects:human,material,technology,management and environment.The variable weight theory is used to determine the risk index weight,the safety risk of hoisting operation is evaluated by the improved matter-element extension model.The risk level is determined by combining the proximity principle with the matter-element extension model,and the fuzzy problem of the risk level boundary which could not reflect the fuzziness of risk level boundary of hoisting construction safety of prefabricated buildings in the past is solved.Finally,a prefabricated construction project in Qingdao is taken as an example to verify the model.The results show that the safety risk level of hoisting operation of the project is low,but it is slightly inclined to the trend of medium risk.Compared with the traditional risk level assessment method,the risk assessment results are consistent,which verifies the feasibility of the model.
