应用剪切波速判别饱和砂土振动液化的研究现状

Saturated Sand Liquefaction Evaluation by Shear Wave Velocity:The Study Situation and Existing Problem

介绍了应用剪切波速判别饱和砂土振动液化的原理 ;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 ;针对以上问题提出一些看法。

Principle of saturated sand cyclic liquefaction evaluation by shear wave velocity was presented. The we summarized some achievements in the value adoption of critical shear strain, methods and apparatus used in the relationship study between liquefaction resistance and shear wave velocity, disturbance evaluation from shear wave velocity and establishment of uniform wave velocity evaluation formula suitable for all kinds of sand. At last put forward several personal advice in this field.
