涪王线高后果区管段泄漏风险因素分析

Risk Factor Analysis of Pipeline Leakage in High-impact Area of Fuwang Pipeline

为了准确了解涪王线四处高后果区管段泄漏风险因素,分析高后果区管段运行期可能存在的主要危害类别,采用故障树分析法对高后果区管段进行泄漏风险因素分析,通过以管道失效为顶事件建立故障树,然后进行最小割集计算,获得了高后果区管段泄漏风险影响因素的重要性排序,为高后果区管段的风险管理提供了依据,以保障输气管道和周边学校的安全。

In order to accurately understand the risk factors of leakage in the high-impact area of the Fuwang line,analyze the main hazard categories that may exist in the high-impact area pipe section,and use the fault tree analysis method to analyze the leakage risk factors of the high-impact area pipe segment,The top event establishes the fault tree,and then performs the minimum cut set calculation,and obtains the order of importance of the risk factors of the high-risk area pipe leakage risk,which can provide the basis for the risk management of the high-impact zone pipe segment and ensure the safety of the gas pipeline and surrounding schools.
