摘　　要：软粘土在波浪循环荷载作用下,会发生变形增加、强度降低的软化现象。软粘土软化特性的深入研究,对指导工程实践、科学预防工程事故,具有重要的学术价值和经济意义。文章依次对国内外关于波浪循环荷载作用下软粘土软化的研究进展、软粘土软化影响因素、软化机理以及现阶段常见的软化模型进行了阐述,并对防治软粘土软化的对策进行了探讨。The increase of deformation and the decrease of strength will occur when the soft clay is under the wave cyclic loading. Study of soft clay softening characteristics is of great value for engineering practice and prevention of engineering accidents. In this paper, the abroad and domestic research progress, factors affecting the softening of soft clay, softening mechanism and common softening models of soft clay were introduced. Then the precaution for softening of soft clay was discussed.
