External disturbance is an important cause of underground pressure pipeline damage, which leads to accidents, and it crucial study the risk damage caused by external come up with proper prevention control measures. We reviewed literature on identification pipelines due was conducted, a list factors formed. Based factors, fault tree analysis carried out disturbances, measures were proposed through calculation minimum cut sets, path structural importance, in hopes providing reference for normal operation pipelines.
