摘要: 为保障铁路运营安全,提升铁路运输组织效率,以大型铁路客运站为研究对象,根据影响铁路客运站安全的各个因素,结合火灾事故特点,选取事故树模型对大型铁路客运站火灾风险事故进行分析;应用有关规则确定火灾事故的最小割集,并选用结构重要度对基本事件的重要性进行定性分析。结果表明:自动报警器系统故障和消防系统故障是影响大型铁路客运站火灾事故的关键因素,客运站日常工作须从预防性控制方面入手,辨识并消除铁路客运站内火灾事故安全隐患,从而为旅客出行提供更好的安全支撑。

关键词: 大型铁路客运站, 危险源辨识, 事故树模型, 最小割集, 结构重要度

Abstract: In order to safeguard the safety of railway operation and improve the organization efficiency of railway transportation, the large railway passenger stations were taken as the research objects. According to the various factors influencing the safety of railway passenger stations and the related characteristics of fire accidents, the fault tree model was chosen to analyze the fire accident of large railway passenger stations. Relevant rules were used to determine the minimum cut set and the importance of basic events was analyzed qualitatively by selecting the structure importance degree. The results show that the failure of automatic alarm system and fire system are the key factors affecting fire accidents at large railway passenger stations. The routine work of passenger stations must start with preventive control measures, identify and eliminate potential security problems in railway passenger stations in order to provide better safety support for travel of passengers.

Key words: large passenger railway station, hazard identification, fault tree model, minimum cut set, structural importance
