主　　题：seismic hazard assessment oil and gas pipeline fault displacement 

摘      要：The purpose of this paper is to adopt the uniform confidence method in both water pipeline design and oil-gas pipeline *** on the importance of pipeline and consequence of its failure,oil and gas pipeline can be classified into three pipe classes,with exceeding probabilities over 50 years of 2%,5% and 10%,***-based design requires more information about ground motion,which should be obtained by evaluating seismic safety for pipeline engineering *** from a city＇s water pipeline network,the long-distance oil and gas pipeline system is a spatially linearly distributed *** the uniform confidence of seismic safety,a long-distance oil and pipeline formed with pump stations and different-class pipe segments should be considered as a whole system when analyzing seismic *** the uncertainty of earthquake magnitude,the design-basis fault displacements corresponding to the different pipeline classes are proposed to improve deterministic seismic hazard analysis（DSHA）.A new empirical relationship between the maximum fault displacement and the surface-wave magnitude is obtained with the supplemented earthquake data in East *** estimation of fault displacement for a refined oil pipeline in Wenchuan MS8.0 earthquake is introduced as an example in this paper.
