为提高我国高速铁路网络(HSRN)面对突发事件的抗毁性和可靠性,保障HSRN平稳而高效率地运营,基于复杂网络理论,构建3个发展时期的HSRN拓扑结构,探究网络的拓扑特性和发展趋势。利用站点重要性综合评价指标挖掘HSRN的重要站点。通过计算网络效率和最大连通子图,分析HSRN在随机攻击和蓄意攻击下的表现。结果表明:我国HSRN在中期发展阶段是以增加网络连通度为主,在长期发展阶段是以丰富集聚效应为主;站点重要性排序显示,武汉、天津、长沙和襄阳将成为不同发展阶段的重要站点;HSRN对随机攻击有鲁棒性,对蓄意攻击有脆弱性。
In order to improve the survivability and reliability of HSRN in China and ensure the smooth and efficient operation of HSRN, this paper constructs HSRN topologies in three developmental stages based on complex network theory to explore the topological structure of HSRN Features and trends. Exploit the comprehensive evaluation index of site importance to mine the important sites of HSRN. By calculating the network efficiency and the maximum connected subgraph, HSRN is analyzed under random attack and deliberate attack. The results show that: HSRN in our country is mainly in the stage of medium-term development with increasing network connectivity, and in the long-term development stage, it is mainly based on the enrichment effect; ranking by site importance shows that Wuhan, Tianjin, Changsha and Xiangyang will be important in different stages of development Site; HSRN is robust to random attacks and vulnerable to deliberate attacks.
