事故树在高层住宅管道PLG泄漏事故分析中的应用

Use of Fault Tree in the Analysis of PLG Leakage through Pipelines in High-rise Building

分析了管道液化石油气(PLG)的泄漏事故,结合某高校高层住宅的实例,应用事故树分析方法,绘制了高层住宅管道液化石油气泄漏的事故树,并计算了结构重要度,估算了基本事件和顶上事件的概率。

Th is paper analyses the leakage problem in the liquefied petroleum gas(LPG)pipelin e in a high-rise residential building by using fault tree method.Based on the case study,the fault tree is made to analyze the leakage cause.The structure i mportance of fault tree is calculated and the probability of basic events and to p event is also estimated.
