为预防突发事件对城市轨道交通网络的影响,提高应变能力、增强运营稳定性,有必要对其网络可靠性进行分析.以上海市轨道交通网络为实证对象,基于L空间和P空间方法建立两种网络拓扑结构,分析其复杂网络的静态特性.提出针对车站删除方法的4种攻击策略,并对各种攻击策略下网络可靠性的变化进行比较分析.结果表明,轨道交通车站网络和换乘网络对随机攻击具有鲁棒性,对蓄意攻击具有脆弱性;动态攻击策略对网络可靠性的影响比静态攻击策略更大.

In order to prepare the influence of accidents on urban rail transit network and improve response capability and operation stability, it is necessary to investigate the reliability of urban rail transit network. Taking the rail transit network in Shanghai as an example, this paper discusses the static characteristics and complexities of two network topologies based on the L space and P space methods. Aiming at four possible attack strategies of stations deleting methods, the paper compares the network reliability under different at-tack strategies. The results show that the rail transit station and the transfer network are robust to random attacks, but fragile to deliberate attacks. Dynamic attack strategies have greater impact on the network reli-ability than the static attack strategies.
