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.
