中文摘要：

以系统工程学为视角,结合北京市2004—2008年地铁运营异常记事信息,运用事故树分析法对城市轨道交通乘客坠落站台事件进行分析。通过分析得出,在现有无屏蔽门的条件下,除去乘客自身原因,乘客坠落站台事件发生的概率主要取决于站台管理措施和引导服务设施设置是否合理。本研究有助于城市轨道交通运营公司对引起该事故发生的各个因素提高警惕意识,也为运营安全管理工作提供理论依据。

英文摘要：

We employ fault tree design form to analyze the accident of passenger platform falling with system engineering,which is based on the data from Beijing subway from 2004 to 2008.Analyzing results show that the accident probability of passenger platform falling depends on platform management policies and platform pilot facilities in the conditions of no screen door and no passenger involvement reason.The paper is favorable for awareness increase against many such accident caused elements and can provide a theoretical reference for the analysis of operational security management.
