摘　　要：在城市轨道交通网络化运营的背景下,构建了轨道交通网络抗毁性分析模型,提出了一种新的换乘站脆弱性测算方法.模型以L,P空间下的平均路径长度、网络效率和有效节点减少率为评价指标,考虑了网络遭受攻击的严重程度,分为一般攻击和严重攻击.以上海市轨道交通网络为例,量化分析了不同程度攻击下L,P空间网络的抗毁性,计算得到了严重攻击下10个最脆弱的换乘站.结果表明,上海市轨道交通网络对一般攻击表现出较强的抗毁性,对严重攻击表现出较差的抗毁性,因此,应做好危险防范工作,降低换乘站发生严重故障导致线路中断运行的风险概率,提高应急水平.Under the background of urban rail transit network operation, the invulnerability analysis model of rail transit network was constructed, and a new method for calculating transfer station vulnerability was proposed. The model took the average path length, network efficiency and effective node reduction rate in L ,P space as evaluation indexes, and considered the severity of network attack, which could be divided into general attack and severe attack. Taking Shanghai rail transit network as an example, invulnerability of L and P space network under attack of different levels were analyzed quantitatively, the 10 most vulnerable transfer stations were calculated under severe attack. The results indicate that Shanghai rail transit network has strong resistance to general attack and poor resistance to severe attack. Therefore, it is necessary to do a good job of risk prevention to reduce the risk probability of line interruption caused by serious faults at transfer stations and improve the emergency level.
