摘要 为有效评价装配式地铁车站施工安全风险,减少施工安全事故发生,保障施工安全,提出基于组合赋权和云模型的风险评价方法。首先,根据国家规范和项目资料,初步识别装配式地铁车站施工安全风险因素;再利用德尔菲法优化风险因素,建立包括6个一级指标和25个二级指标的装配式地铁车站施工安全风险评价指标体系;然后,采用熵权法和组合数有序加权(C-OWA)算子确定指标的组合权重,进而结合云模型确定风险评价等级;最后,基于某装配式地铁车站项目验证上述评价方法。结果表明:该项目评价等级为较低风险,与施工现场实际情况基本一致,但人员和施工技术的风险等级为中等,在采取安全防控措施时应重点考虑。 In order to effectively evaluate the construction safety risk of prefabricated subway stations,reduce construction safety accidents and ensure construction safety,a risk evaluation model based on a combination weighting and cloud model was proposed.Firstly,the construction safety risk factors were identified based on national standards and project information and then optimized by the Delphi method,to establish a construction safety risk assessment index system including 6 first-level and 25 second-level indexes.Then,using the entropy weight method and continuous ordered weighted averaging(C-OWA)operator to determine the index weight and the cloud model to determine the risk assessment level.Finally,the above evaluation method was verified based on a prefabricated subway station project.The results show that the evaluation grade of the project is relatively low risk,which is consistent with the actual situation of the construction site.However,the risk level of personnel and construction technology is medium,which should be given priority consideration when taking safety prevention and control measures.
