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
