4) city natural gas pipeline
城镇天然气管道
1.
The quantitative method for risk analysis of city natural gas pipeline is put forward based on event tree analysis (ETA) and fault tree analysis (FTA).
提出了以事件树分析为主线,结合故障树分析的城镇天然气管道风险定量分析方法:将管道泄漏分为渗透泄漏、穿孔泄漏和开裂泄漏3种泄漏模式;以管道泄漏为故障树分析的顶事件,分析管道泄漏的原因和概率;以管道泄漏为事件树分析的初因事件,分析管道泄漏在各种情况下造成的后果序列;以故障树分析事件树中后续事件的概率,以初因事件的概率和后续事件的概率计算后果事件的概率;分别对各个后果事件进行后果危害程度分析和经济损失估计;累加每个后果事件的经济损失数学期望,得到整个管道系统的风险值。
