The safety management of prefabricated building construction is mainly concentrated in the early stage of the process,the safety assessment system is not complete,and the risk monitoring of the whole process is difficult to achieve,so the judgment of safety risks needs to be checked in the whole process of the risk control of the construction of prefabricated projects.In order to improve the accuracy of risk assessment,the study constructs an engineering risk assessment index system for a prefabricated project based on entropy weight method,and obtains the results of construction safety risk assessment for the project.The results show that the comprehensive weighted correlation value of this project is 0.1390,the characteristic value of the comprehensive level variable is 2.6916,and the overall risk grade of Ⅱ is consistent with the expert evaluation result,which belongs to the relative safety grade,indicating that the model has a high accuracy in the safety risk assessment of prefabricated structure.
