摘　　要：为解决国家“西气东输”工程所面临的重要技术难题 ,对国内外在长距离输送管道的地震反应与稳定性研究领域内的现状及所存在的问题进行了综述 ,包括土 -管系统模型的建立、地震激励的输入以及管线的地震反应分析方法等 ,分析了有关理论研究和工程技术的发展趋向 ,指出进一步研究各种因素对管道抗震性能影响的范围与程度 ,力学模型的进一步补充与完善 。To solve the important technical difficulties of transporting gas from the West to the East of China, summarized are the state-of-the-art and existing problems in the field of the aseismatic response and the bucking of the long distance transportation pipelines, including the modeling of soil-pipe system, aseismatic excitation and the analysis methods of aseismatic of the pipes. The trend of the relative theoretic research and project technology is analyzed. The research needs in this field, such as the further research in the range and degree of all the factors' influence to the aseismatic capability of the pipes, the further complementarity of the mechanics models and the further retouch of the computing means are presented.
