跨断层埋地输油气管道抗震研究述评

Study on Earthquake Proof of Buried Oil and Gas Pipelines in Geological Crossing Faults

埋地输油气管道地震破坏通常发生在活动断层,因此,有必要对目前国内外埋地管道的断层错动反应进行分析,以避免或减轻跨断层管道在未来地震中的破坏。综述了理论解析法、数值分析法和试验研究法等三种国内外近几年跨断层埋地输油气管道断层错动反应分析方法,比较三种方法的优缺点,指出各方法中存在的问题。从新建管道项目和已建管道两方面着手,分析目前常用的跨断层埋地管道的抗震措施,提出今后跨断层埋地管道的研究趋势。

Earthquake damage of buried oil and gas pipelines often happens in active faults. Therefore, it is necessary to analyze fault movement reactions of buried pipelines to avoid or mitigate such damage. Reviewed are such methods as theoretical analysis method, numerical analysis method and test method used at home and abroad in recent years for analysis on fault movement reactions, compared are advantages and disadvantages among different methods and stated briefly are some problems existing in current analysis methods. Finally analyzed are earthquake resistant measures commonly used at present in new-built and existing oil and gas pipelines and forecasted are future research trends of buried oil and gas pipelines in geological crossing faults.
