摘　　要：研究城市轨道交通网络结构特性对轨道运营过程中的维护管理工作具有重要意义。基于复杂网络理论,采用Space-L建模方法构建重庆市轨道交通网络拓扑结构,实证分析该网络的复杂特性;选取网络效率和最大连通子图比例两项指标,仿真分析网络面临攻击的剩余功能,进而评估其鲁棒性。结果表明:重庆市轨道交通网络属于无标度网络和小世界网络模型,面临突发运营事件具有一定的鲁棒性,但在蓄意攻击状态下的鲁棒性较差;要重视网络中度值较大、介数较大站点风险防范措施的建设。研究结果可为重庆市轨道交通日常运营维护工作提供数据参考。Studying the structural characteristics of urban rail transit network is of great significance for maintenance and management during rail operation.Based on the theory of complex network,the Space-L modeling method was used to construct the topology structure of Chongqing’s rail transit network,and the complex characteristics of the network were empirically analyzed.Selected two indicators:network efficiency and the proportion of the largest connected subgraph,simulated and analyzed the remaining functions of the network facing attacks,and then evaluated its robustness.The results show that Chongqing’s rail transit belongs to scale-free network model and small world network model,it has a certain degree of robustness in the face of sudden operational events,but the robustness is poor under intentional attacks.The research results provide data reference for the daily operation and maintenance of Chongqing’s rail transit,and it is important to pay attention to the construction of risk prevention measures for sites with high node degree and node betweenness in the network.
