摘要:
脆弱性分析是提升城市轨道交通系统干扰应对能 力的关键性课题。 运用复杂网络原理,构建城市轨道交通网 络模型,建立多维度的城市轨道交通网络脆弱性评价指标体 系,运用计算机仿真技术,基于线路失效模式,以线路组合方 式对可能出现的故障情境进行模拟,并以北京、上海两地为 例开展实证对比。 研究表明,城市轨道交通网络在核心线路 或线路组合失效的情况下,表现出较高脆弱性;核心线路和 非核心线路的脆弱性影响差异较大;北京城市轨道交通网络 基于线路失效的脆弱性要显著高于上海。 同时,对指标方法 的现实意义和适用性问题进行了讨论。
Abstracts:
Vulnerability analysis is a critical issue to improve the interference response ability of urban rail transit system. Using the principle of complex network, urban rail transit network model is constructed,and a multi -dimensional urban rail transit network vulnerability evaluation index system is established. Adopting computer simulation technology,based on the line failure modes,possible failure scenarios are simulated in the form of line combinations,and Beijing and Shanghai are taken as the actual cases for comparative verification. The research result shows that the urban rail transit networks exhibit higher vulnerability in the occurrence of failure in core line or line combination. The core and non-core lines have significant differences in their impact on the vulnerability. The vulnerability of Beijing urban rail transit network from line failure is significantly higher than that of Shanghai. The practical significance and applicability of the index method are discussed.
