摘　　要：腐蚀是引起埋地输气管道泄漏和破裂的主要因素。针对引起埋地输气管道腐蚀失效的各个因素进行系统分析,建立以埋地输气管道腐蚀失效为顶事件的埋地输气管道腐蚀失效故障树,结合管道腐蚀破坏机理和故障树分析方法,分析导致管道腐蚀产生的因素,得到故障树的各阶最小割集和引起埋地输气管道发生腐蚀失效的主要因素,并提出了相应的措施以提高埋地输气管道的可靠性。Corrosion is a main factor resulting in buried gas pipeline leak and rupture. Based on systematic analysis on corrosive failure factors of gas pipeline, the fault tree of corrosive failure of buried gas pipeline is put forward. In addition, on the basis of corrosion theory of gas pipeline and the fault tree analysis method, relevant measures are presented in order to improve the reliability of buried gas pipeline.
