摘　　要：首先介绍了应用剪切波速判别饱和砂土振动液化的原理;然后从临界剪应变取值、砂土的抗液化能力与剪切波速相关关系的研究方法与设备、用剪切波速进行扰动评价、建立适用于不同土类的统一判别式四方面总结了国内外学者在该领域的一些研究成果及存在问题;最后针对以上问题提出作者的一些看法。Principle of saturated sand cyclic liquefaction evaluation by shear wave velocity is presented. Then some achievements in the choosing value of critical shear strain, the methods and apparatus used in the relationship study between liquefaction resistance and shear wave velocity, the disturbance evaluation by the shear wave velocity, and the establishment of uniform wave velocity evaluation formula suitable for all kinds of sand are summarized. At last several advices in this field are proposed.
