摘　　要：在地震动作用下,土石坝等土工建筑物与地基将产生不可恢复的瞬时失稳滑移或永久变形。从国内外发展现状及所取得的主要研究进展和近期发展动向等角度,对土工建筑物地震永久滑移变形的各种简化计算方法进行了系统的综述和总结,进而对各种分析方法及其适用条件进行了评述,最后对今后关于这一专题所应开展的研究提出了建议。For the earth structures and foundations subjected to earthquake shaking, a certain sliding movements or permanent deformations will be initiated by the transient and/or cyclic loading induced by earthquake. The amount of the seismically-induced irrecoverable sliding movements or residual deformations is a key parameter for evaluating aseismic stability of earth structures. In the paper, a state-of-the-art review on this special issue is systematically made and then the instructive comments are given for the various procedures for assessment of the sliding movements and permanent deformations and the applicable conditions of these methods. The suggestions for the further advanced study on this topic are presented.
