摘要： 根据饱和砂土剪切波速与其抗液化强度的相关性原理，利用剪切波速与振动三轴联合实验装置，进行了控制饱和砂土初始剪切波速的振动液化实验，依据实验结果建立了剪切波速与抗液化强度的定量关系。最后用现场勘查数据对此定量关系进行验证，结果表明：该关系式对实际 66 个未液化地点的判别准确率达到 81.2 %；对 108 个实际液化地点的判别准确率达到 62.8 %；平均判别准确率达到 69.5 %。

Abstract: According to the dependence between Shear wave velocity and cyclic liquefaction resistance of saturated sand, combined tests were carried out for remoldeld saturated sands, during which the shear wave velocity of saturated sand sample was fistly tested in the cyclic triaxial cell and then the normal cyclic liquefaction test performed. Then, by analysing the test results, the quantative relatiobship between shear wave velocity and the cyclic liquefaction resistance of saturated sand was obtained. At last, 174 earthquake sites data was utilized to verify the reliability of the relational expression. The results show among the 66 non liquefied sites the correct rate of the expression is 81.2 % and among the 108 liquefied sites the correct rate is 62.8 % in general, the average correct rate of the relational expression is 69.5 %.

Key words: shear wave velocity of soil, cyclic liquefaction of saturated sand, cyclic liquefaction resistance, dynamic triaxial test
