【Abstract】 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.更多还原
