煤气管道的震害率分析
|
摘要
埋地管道的地震危险性分析方法可以分为理论分析法和经验统计法。震害率是经验统计法中常用的一个概念。埋地管道在地震中破坏的主要原因是地面运动和场地土液化等引起的场地土失效,另外管线的接口类型、管材、管径等也是决定其震害的因素。在查阅相关文献的基础上,对埋地管道的震害率分析方法进行了综述,并运用经验统计法提出了便于使用的煤气管道震害率估算表达式。
The analysis methods of earthquake risk of buried pipeline could be divided into theoretical approach and empirical approach.Earthquake damage ratio is a usually used concept in empirical approach.The main factors that lead to damage to buried pipe in earthquakes are earthquake ground motions (wave propagations) and ground failure induced by liquefaction etc.In addition,there are other factors—such as joint,material,diameter of pipe and so on.In this paper,analysis methods of earthquake damage ratio of buried pipe are summarized,and damage ratio of gas pipe is put forward based on empirical approach.
