基于可拓学理论的装配式住宅施工过程安全风险评价研究

Research on Safety Risk Assessment in Prefabricated Residential Construction Process Based on Extension Theory

研究结合影响装配式住宅施工过程安全风险的因素,构建了装配式住宅施工过程安全风险指标体系。通过运用改进综合权重法来确定各指标权重,并结合可拓学理论构建了综合模糊可拓评价模型。最后,通过装配式住宅的实际案例进行验证,发现该评价模型能够客观系统地评估装配式住宅施工过程中安全风险状况,同时能及时准确地诊断出安全隐患,为决策者提供建议,从而减少施工过程中不安定因素。

Combined with the factors that influence the safety risk of the prefabricated residential construction process,the safety risk index system of the prefabricated housing construction process is constructed.Each index weight is calculated by using the improved comprehensive weight method,and also a comprehensive fuzzy extension evaluation model is set up based on Extension Theory.Finally,the actual case is taken to verify and find that the model can systematically evaluate the safety risk in fabricated residential construction process and timely and accurately diagnose the security hidden danger,which can provide recommendations for decision-maker to reduce the unstable factors in the construction process.
