断层作用下埋地管道应变分析方法研究进展

Research progress of strain analysis methods for buried pipelines under faulting process

  • 摘要: 断层是埋地管道在强震区的主要威胁,管道在断层作用下将产生较大的拉压应变而失效。通过调研国内外断层作用下埋地管道应变分析的相关研究,分别从解析分析、数值模拟、试验研究3个方面论述了国内外的研究进展,尤其是近年来国外在试验研究方面的突破。通过对比分析评述了目前的研究趋势,指出了国内外对于断层作用下管道应变分析研究的差距。结合工程实际需求,提出了断层作用下管道应变研究方法的不足和今后的发展方向。

     

    Abstract: Active fault is one major threatening factor for buried pipelines in strong seismic zones. Pipelines get failed due to the large tension or compression strain caused by the faulting. After the domestic and foreign strain analysis methods for buried pipelines under the action of faulting were reviewed, their research progress was illustrated from the aspects of analytical analysis, numerical simulation and experimental study, especially the recent breakthroughs of experimental study all over the world. Then, their current research trends were comparatively analyzed and the gap between domestic research and foreign research was pointed out. And finally, the deficiencies and future development targets of these strain analysis methods were proposed on the basis of actual engineering requirements.
