摘　　要：为保障城市轨道交通运输网络的安全运营,使城市轨道交通网络改、扩、建优化策略更具有针对性,提升网络抗毁能力。通过复杂网络理论构建城市轨道交通网络路网模型,该模型引入虚拟换乘边概念,便于准确地描述网络中边的权重,并通过提出改进的边权函数以及交通流动态分配原则,建立了网络级联失效模型。以郑州市城市轨道交通网络进行了实证分析,结果表明:改进后的城市轨道交通网络级联失效模型能更为准确地仿真网络级联失效过程;网络在选择性攻击和随机性攻击下选择性攻击网络所呈现的鲁棒性较差。可见对于城市轨道交通网络优化时,应该重视提升关键节点的鲁棒性,实现网络高效运转。In order to ensure the safe operation of the urban rail transit transportation network,the optimization strategy of the transformation,expansion and construction of the urban rail transit network should be specific to improve the network s anti-destruction ability.The network model of urban rail transit network was constructed through the complex network theory,which introduced the concept of virtual transfer edge to accurately describe the weight of edge in the network.And the network cascade failure model was established by proposing the improved edge weight function and the dynamic distribution principle of traffic flow.The empirical analysis of Zhengzhou urban rail transit network shows that the improved cascade failure model can simulate the cascade failure process more accurately.Under selective attack and random attack,the robustness of selective attack networks is poor.Therefore,when optimizing urban rail transit network,attention should be paid to improving the robustness of key nodes and realizing efficient operation of the network.
