Research of Risk Identification and Prevention of Underground Pressure Pipelines Damage Caused by External Disturbance

Abstract

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