| Abstract: | 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. |
