基于模糊集与DS证据理论的装配式建筑施工安全风险评价

Safety risk assessment of prefabricated building construction based on fuzzy set and DS evidence theory

针对装配式建筑施工安全风险频发的问题,结合现场调研与已有研究进行风险因素归类,建立安全风险评价指标体系。采用C-OWA算子对指标赋权,利用模糊集与改进DS证据理论耦合各个指标,构建装配式建筑施工安全评价模型。通过对QD市万科新都会一期项目进行实例分析,评价结果符合预期,说明该模型具有一定的可行性和有效性。

In view of the frequent occurrence of safety risks in the construction of prefabricated buildings, the risk factors are classified based on the field investigation the existing research, and the safety risk evaluation index system is established. C-OWA operator is used to weight the indicators, and the fuzzy set and improved DS evidence theory are used to couple the indicators, and the construction safety evaluation model of prefabricated buildings is constructed. Through the example analysis of QD Vanke Xinduhui Phase I project, the evaluation results meet the expectation, which shows that the model has certain feasibility and effectiveness.
