摘　　要：在装配式建筑施工风险管控中需要全程进行安全风险的识别,安全风险评价模型的建立对施工安全管理有重要意义。为提高风险评价的准确性,提出基于物元可拓理论和信息熵的熵权物元可拓模型。构建风险评估模型的指标体系,结合物元可拓理论和信息熵,建立熵权物元可拓模型用于A公司的施工安全风险评价。就A公司而言,该项目施工安全的综合加权关联度值为0.1390,风险等级的划分结果为II级,属于较为安全的等级;综合级别变量特征值为2.6916。综上所述,该公司的装配式建筑施工项目属较为安全的等级,与专家的评分结果具有一致性,表明该模型在装配式建筑施工安全风险评价中具有准确性。In the risk management and control of prefabricated building construction,it is necessary to identify the safety risks in the whole process.The establishment of the safety risk assessment model is of great significance to the construction safety management.In order to improve the accuracy of risk assessment,an entropy weighted matter-element extension model based on matter-element extension theory and information entropy is proposed in this study.Firstly,the index system of risk assessment model is constructed,and then the entropy weighted matter-element extension model is established for the construction safety risk assessment of Company A by combining matter-element extension theory and information entropy.As far as Company A is concerned,the comprehensive weighted correlation value of the project construction safety is 0.1390,and the risk level is classified as Level II,which belongs to a relatively safe level;The characteristic value of comprehensive level variable is 2.6916.The results show that the prefabricated building construction project of the company belongs to a relatively safe level,which is consistent with the expert scoring results,indicating that the model is accurate in the safety risk assessment of prefabricated building construction.
