摘　　要：为提出一种用于评估近接运营地铁的城市地下工程施工安全韧性的方法,首先,通过对近接施工的3个方面(新建地下工程、地层、既有地下结构)以及2个维度(技术和管理)的分析,建立一个较为完整的韧性指标体系;其次,结合层次分析法、熵权法和博弈论,提出韧性指标体系的权重组合分析方法;同时,基于集对分析理论,提出研究体系复合性能Q的连续评估方法;最后,从“最大损伤”和“累计损伤”2个角度提出韧性R的综合评估计算公式,并将其应用于具体工程案例的分析。研究结果表明:1)新提出的韧性评估方法与传统的风险评估方法可以相互印证,且新的韧性评估方法考虑因素更为全面;2)提出的系统复合性能Q包含3个维度,即既有地下结构(Q_(A))、地层(Q_(B))、新建地下工程(Q_(C)),比传统的评估理论更全面;3)随着既有地下结构的动态指标限值越来越严格,系统复合性能Q的评估结果对应有所下降。A resilience assessment approach is proposed for the construction safety of urban underground engineering adjacent to an operating metro.First,three key factors involved in close construction(existing underground structure,formation,and newly-built underground engineering)and two dimensions(technology and management)are analyzed,establishing a relatively complete resilience index system.Second,a weight combination analysis approach for the resilience index system is developed using the analytic hierarchy process,entropy weight approach,and game theory.Furthermore,a method for the continuous evaluation of the complex performance Q of the system is proposed based on the theory of set pair analysis.Finally,an evaluation formula for resilience R is proposed from the aspects of maximum damage and cumulative damage,which is then applied to the analysis of a case study.The main findings include:(1)The newly proposed resilience assessment method can be mutually verified with traditional risk assessment method,and the new method considers more comprehensive factors.(2)The composite performance Q of the proposed system contains three dimensions,namely,existing underground structure(Q_(A)),formation(Q_(B)),and newly-built underground engineering(Q_(C)),showing more comprehensiveness than the conventional assessment theory.(3)As the limits of dynamic indices of existing underground structures become increasingly stringent,the evaluation results of the system's composite performance Q correspond to a decrease.
