摘　　要：就砂土液化的定义以及有关的一些基本概念进行了讨论 ,对稳态概念和它在饱和砂土液化判别中的应用进行了综述 ,并讨论了与稳态强度有关的一些问题。最后还指出饱和砂土液化需要进一步研究的问题。The definitions of liquefaction and some basic concepts are discussed.An attempt is made to clarify some misunderstandings in Chinese geotechnical engineers.It may be arisen through the use of different terminology.The development of the steady state deformation and the steady state line are introduced.Moreover,the application of basic concepts to discriminate the liquefaction of saturated?soil is reviewed.Some problems relate to the steady state strength are discussed.The suggestions are provided with a list of some problems worthy to be further studied

关 键 词：砂土液化 稳态强度 流滑破坏 循环活动性
