摘　　要：通过大量的现场调查发现,引起集输管网发生失效的直接原因是管道与附件设备的失效。对集输管网失效的各因素进行了综合性的分析,建立了以集输管网失效为顶事件的故障树。考虑44个基本事件,使用下行法对集输管网失效故障树进行分析,得出了系统全部52个最小割集,而且对故障树进行了定量分析。对集输管网进行定性分析找出集输管网最薄弱的环节,可为老管网的维护和新管网的设计提供理论指导。The direct cause of gathering pipe network failure was the failure of the pipeline and accessories equipments according to a lot of field investigation.The fault tree was established as the top event of gathering pipeline failure on the basis of the comprehensive analysis of gathering pipeline network failure factors.Considering about the 44basic events,the descending method was used to analyze the gathering pipeline network failure fault tree,and obtained all 52 minimum cut sets in the system.And the quantitative analysis of the fault tree was carried on.The qualitative analysis was carried on the gathering pipe network and the weakest link was found out in gathering pipe network,which could maintenance the old pipeline network and provide theoretical guidance for the design of the new pipeline network.
