事故树在铁路运输液化石油气安全分析中的应用

在分析铁路运输液化石油气途中可能出现危险的基础上,简要介绍事故树分析方法,并利用该方法分析铁路运输液化石油气过程中发生事故的主要原因,编制铁路运输液化石油气事故树,对该事故树进行定性和定量分析,求出其最小割集、最小径集和结构重要度,最后依据分析结果提出预防事故的措施。

Application of Fault Tree on Safety Analysis of Railway LPG Transportation

Based on analyzing the danger maybe occurred during railwy LPG transportation, this paper intro-duces the Fault Tree method. By using this method, the main reason of accident during railway LPG transporta-tion was analyzed, the fault tree of railway LPG transportation was established, then was taken qualititiveness andquantitiveness analysis, so as to get minimum cut set, minimum path and structure importance. In the end, theaccident prevention measures were provided based on analysis result.
