埋地管道通过活动断层区的研究

活动断层所产生的急剧错动性的地面运动,会导致如断层位移、滑坡和地陷等,对埋地管道系统造成严重的影响。研究表明,地震已严重破坏了埋地的油、气、水和污水管道,其后果表现为管道的断裂与严重扭曲。由于地震活动的危害,国内外目前对穿过活动断层区埋地管道的设计均十分重视。分别从埋地管道震害原因、埋地管道通过平推断层的当前的研究以及通过逆冲断层区的研究现状等方面,综述了埋地管道通过活动断层区的研究情况,提出了埋地管道通过逆冲断层区存在的主要问题。

Study on Buried Pipelines Passing Through Active Fault Zone ,

The hazards from sharp ground displacing activity caused by active fault, such as fault displacement, landslide and collapse, etc. will make a significant effect on buried pipeline system. Studies demonstrate that earthquake has made serious damages to buried oil, gas, water and sewage pipelines, presenting pipeline rupture and serious distortion consequently. Because of the hazards made by seismic activity, at present more attention has been paid to the design of buried pipelines passing through active fault zone both at home and abroad. The article describes study situations individually on the pipelines passing through active fault in the aspects of the reason of pipeline seismic hazard, the present study on the pipeline passing through wrench fault and the study situation on the pipeline passing through thrust fault and put major questions existed in the pipeline passing through thrust fault.
