摘　　要：为科学评估新冠肺炎疫情对省域高速铁路运营网络的影响,根据不同的疫情防控场景,基于复杂网络理论构建高速铁路运营网络脆弱性评估模型,并以山东省高速铁路运营网络为例进行仿真分析。结果表明:运营网络属于小世界网络,重要站点大多位于市级中心城区;运营线路感染场景下网络表现出更强的脆弱性;无论哪种攻击场景,蓄意攻击对高速铁路运营网络的影响均大于随机攻击;从不同脆弱性指标看,相比于反映网络连通水平的网络效率与最大连通子图指标,正常营运车次占比指标在不同攻击场景下呈现出更强的脆弱性。In order to scientifically evaluate the impact of the COVID-19 on the provincial high-speed railway operation network, this paper constructs a vulnerability assessment model of the high-speed railway operation network based on the complex network theory according to different epidemic prevention and control scenarios,and takes the high-speed railway operation network in Shandong province as an example for simulation analysis.The results show that the operation network belongs to the small world network,and most of the important stations are located in the city center. The network is more vulnerable under the scenario of operation line infection. No matter what kind of attack,the impact of deliberate attack on high-speed railway operation network is greater than that of random attack. From the perspective of different vulnerability indicators, compared with the network efficiency and maximum connectivity sub graph indicators that reflect the level of network connectivity, the indicator of the proportion of normal operating trains shows stronger vulnerability in different scenarios.
