摘　　要：通过多年的研究,人们对饱和砂土液化有了很深的认识。在Seed简化法,剪切波速法和标准贯入试验等判别的方法的研究方面也取得了很多的成果。本文主要介绍了我国广泛应用的标准贯入试验的方法,以及应用数值方法如何更好的判断场地的抗液化性。提出应用室内的微型贯入试验来判断饱和砂土液化的展望。The study of saturation sand liquefaction has been lasted many years,and we have deep understanding of it.We also got a lot of achievement on some methods,such as the Seed simplified method,shear wave velocity method and standard penetration test（SPT）.In this paper,mainly introduce SPT widely utilized in our country,and how to use numerical method to determine the anti-liquefaction of site.Put forward the prospect that utilize minisize penetration test to judge the liquefaction of saturated sand.
