【摘要】:为对高铁运营过程中具体环节进行风险分析,确保高铁安全运营,提出构建高铁运营安全的Bow-tie模型.首先,明确高铁运营过程中的风险事件;然后,通过对高铁运营过程中3种典型风险事件:高速列车脱轨、列车冲突以及列车火灾,进行事故树定性分析,计算各基本事件的重要度,找出对顶事件的影响程度最大的基本事件;最后,按消除源头、风险预防、防止恶化及减轻后果的优先级在高铁运营过程中加以实施控制措施,提出事故前预防屏障及事故后保护屏障,构建高铁运营安全Bow-tie模型.研究结果表明:Bow-tie模型可以应用于目前高速铁路运营风险管理的日常教育培训、突发情况的应急处理及事故发生后的调查分析.
[Abstract]:In order to analyze the risk and ensure the safe operation of high-speed railway, a Bow-tie model of high-speed railway operation safety is proposed.First of all, the risk events in the operation of high-speed railway are defined. Then, through the qualitative analysis of three typical risk events in the operation of high-speed railway: high-speed train derailment, train conflict and train fire, the accident tree is analyzed qualitatively.Calculate the importance of each basic event, find out the basic event that has the greatest impact on the top event; finally, implement the control measures during the operation of the high-speed railway according to the priority of eliminating the source, preventing the risk, preventing deterioration and mitigating the consequences.The pre-accident prevention barrier and post-accident protection barrier are proposed, and the Bow-tie model of high-speed railway operation safety is constructed.The results show that the 1: Bow-tie model can be applied to the daily education and training of risk management in high-speed railway operation, the emergency treatment of emergencies and the investigation and analysis of accidents.
