摘　　要：在突发事件下,从地铁网络拓扑结构和客流量2个角度综合考虑,提出基于客流量加权的网络全局效率。基于复杂网络理论,构建地铁网络拓扑结构,对网络特征指标进行分析,并提出基于网络全局效率的地铁网络韧性评估方法和基于遗传算法的地铁网络恢复时序优化模型。以西安地铁网络为研究对象,采用5种不同恢复策略下的恢复时序方案对西安地铁网络失效站点进行修复,在此基础上提出最优修复策略。结果表明:①在2种突发事件下,基于遗传算法的恢复策略为最优恢复策略;②突发事件1(洪水倒灌)线性站点失效下的不同恢复策略对网络韧性的影响更为明显;③在相同恢复策略下,突发事件1的网络韧性均高于突发事件2(暴力事件)的网络韧性。Under emergencies,the global efficiency of the network based on passenger flow weighting was proposed through the comprehensive consideration of the two perspectives of metro network topology and passenger flow.Based on complex network theory,a metro network topology was established,and network characteristic indicators were analyzed.A resilience assessment method for metro networks based on the global efficiency of the network and an optimization model for metro network recovery timing based on genetic algorithms were proposed.By using the Xi’an Metro Network as the research object,the optimal recovery strategy for failed stations in the Xi’an Metro Network was proposed based on the recovery timing schemes under five different recovery strategies.The results indicate that:①Under two distinct emergencies,the recovery strategy based on genetic algorithms proves to be the optimal approach.②The impact of different recovery strategies under linear station failures during emergency 1(backflow of floodwater)is more pronounced.③Under the same recovery strategy,the network resilience of emergency 1 surpasses that of emergency 2(violent incident).
