The main research work and its results are: 1Empirical results are analysed for the relations of fault displacement and earthquake magnitude, and difference between permanent ground deformation and maxium dynamic relative displacement on the two sides of fault; 2An analytic method is proposed for resopnse of a buried pipeline due to earthquake fault movement; 3A new shell model with an equivalent boundary and relted finite element analysis method are proposed for estimating response of a buried pipeline under large fault movement; 4By the proposed method, damage performance of water supply steel pipelines with large diameter is simulated to the real cases in Kocaeli Earthquake and Ji-Ji Earthquake, and simulating results show the real failure mode of pipes is revealed; 5Effects of overlying soil and soft/hard interlayers are analyzed on ground rupture mode and degree due to earthquake fault, and some earthquake rupture phenomena in soil layers are theoretically described for the first time; 6Pipeline response characters are discussed for the case of considering effects of soil layers on ground rupture mode; 7Research results and proposed method are applied in seismic analysis of pipline acrossing fault in the Gas Tansportation Project from West to East in China.

主要工作和成果包括：1）分析了不同断层位错形式下地表破裂位错量与震级之间的经验关系，并基于集集地震近断层记录分析了断层两侧永久地面变形和地震动相对位移幅值之间的差别，为合理地考虑地震断层位错地面变形动态影响提供了依据；2）发展了断层位错地面大变形下管线反应分析模型并给出物理概念明确、简单实用的解析分析方法；3）建立了断层位错下埋地管线反应分析的等效边界壳模型有限元方法，方法中引入了以非线性弹簧形式模拟离断层较远处管段影响的等效边界，简化了计算模型并突出了近断层处管体反应；4）利用等效边界壳模型方法，对土耳其地震和集集地震中大口径埋地管线震害进行了模拟，结果表明所提方法可以更清地解释震害所表现的管体破坏特征；5）研究了覆盖土层和软硬夹层的存在对断层位错地面破裂形式和程度的影响，首次从理论上解释了某些地震地表破裂现象；6）探讨了考虑土层对断层位错地面变形影响的管体反应特征；7）本项目成果已在西气东输工程的管道跨断层抗震问题分析中得到了应用。
