为保障铁路系统在灾害风险中的运营安全,进行铁路系统面对灾害风险防控能力的研究。将韧性概念应用于铁路系统领域,界定韧性铁路系统的内涵和特征,构建适用铁路运营的韧性指标选取框架;确定影响铁路系统韧性的变量因素及多种因素间的关系。通过收集国内铁路事故调查报告,基于贝叶斯网络建立铁路系统韧性网络推理模型,提出量化铁路系统韧性指标;通过改变模型中的网络节点属性,分析韧性影响因素对铁路系统的贡献程度,确定事故风险的关键因素,切断风险源传播路径,提升铁路系统自身抗灾能力。研究结果表明:为了确保铁路系统在灾害冲击下的正常运行状态,必须提高铁路系统的应急储备与防灾措施的冗余,...

In order to ensure the operational safety of the railway system,research on the prevention and control capability of the railway system in the face of disaster risks was conducted.A concept of resilience was introduced railway systems.The meaning and characteristics of resilient railway systems were defined.A framework for selecting resilience indicators applicable to railway operations was constructed.To determine the variable factors affecting the resilience of railway systems and the relationship between multiple factors,railway accident investigation reports were collected,and a network mo...
