摘　　要：研究目的:为提高地铁工程安全管理水平,将韧性理论引入安全管理领域。从三元空间安全理论出发,采用二维云模型进行地铁工程施工安全韧性评价。首先,从三元空间的物理空间、社会空间、信息空间出发构建地铁工程施工安全韧性分析框架,参考相关文献建立地铁工程施工安全韧性评价指标体系;然后,兼顾韧性的防御特性和恢复特性,以防御和恢复作为二维云模型的维度建立地铁工程施工安全韧性评价二维云模型,利用云发生器MATLAB编程计算韧性标准云和评价云的云数字特征,生成云滴及韧性云图,对比评价云图和标准云图,结合贴近度来判定安全韧性等级;最后,进行实例分析。研究结论:(1)韧性理论引入安全管理领域,为地铁工程安全管理实践提供了新理念;(2)从物理空间、社会空间、信息空间出发,建立了包括人员因素、材料因素、设备因素、技术因素、管理因素、环境因素、信息因素七个准则层共24个评价指标的安全韧性指标体系;(3)对青岛市地铁5号线某车站工程施工安全韧性水平的综合评价结果为“中度韧性”(Ⅲ级),在工程进行中不仅要注重安全风险防御,还应该注重加强快速恢复能力;(4)二维云模型,将韧性的防御特性和恢复特性综合考虑,云图更直观,可视化更强,可为地铁工程安全韧性评估提供新思路。Research purposes:In order to improve the safety management level of subway projects,the resilience theory is introduced into the field of safety management.Based on the ternary space safety theory,the two-dimensional cloud model is introduced into safety resilience evaluation of the subway engineering construction.Firstly,the safety resilience analysis framework of subway engineering construction is constructed from the physical space,social space and information space of ternary space.The safety resilience evaluation index system of the subway engineering construction is established by referring to the relevant literature.Then,the two-dimensional cloud model of subway engineering construction safety resilience evaluation is established with defense and recovery as the dimension of two-dimensional cloud model.The digital characteristics of resilience evaluation cloud are calculated by cloud generator of MATLAB software,and the two-dimensional evaluation cloud diagram is generated by MATLAB software.The evaluation cloud was compared with the standard cloud diagram to express the resilience level of the engineering system,and the closeness was calculated to ensure the accuracy of the evaluation results.The model is adopted to evaluate the safety of subway engineering.Research conclusions:(1)The introduction of resilience theory into safety management provides a novel concept for the practice of subway engineering safety management.(2)A safety resilience index system is established,encompassing 24 evaluation indicators grouped into seven standard layers,which include personnel factors,material factors,equipment factors,technical factors,management factors,environmental factors,and information factors.(3)The evaluation result indicates a"moderate toughness"level(gradeⅢ).In the course of the project,we should not only pay attention to the security risk defense,but also pay attention to strengthen the rapid recovery ability.(4)The two-dimensional cloud model,which comprehensively considers the defense and recovery c
