摘　　要：导致输气管道失效的直接原因是管道泄漏和断裂。为解决管道泄漏和断裂问题,采用故障树分析法对引起新建输气管道泄漏和断裂的基本原因进行了系统分析,建立了新建输气管道失效故障树,求出其各阶最小割集,并对其结构重要度进行了分析排序,从而找出导致新建输气管道失效的主要因素,提出了相应的改进措施。The direct reason causing gas pipeline failure is leaking and fracture of pipeline.Basic factors causing the new gas pipeline leaking and fracture are systematically analyzed and a fault tree of new gas pipeline failure is set up in the paper.Accordingly,the minimum cut set of each order of the fault tree is obtained.In addition,structure importance has been analyzed and sorted to find out the key failure factors of new gas pipeline,and the relevant measures have been presented.
