Cyclic liquefaction resistances of undisturbed and remolded saturated loose silts with the same shear wave velocity

The correlation between cyclic liquefaction resistance of undisturbed and remolded saturated loose silts was studied using the cyclic triaxial apparatus with measurements of shear wave velocity.It was shown that the variation of peak-to-peak axial strain of undisturbed saturated specimens was the same as that of remolded saturated specimens.If the initial shear wave velocity of remolded saturated specimens was restored to that of undisturbed saturated specimens,the cyclic liquefaction resistance of remolded specimens was also restored to that of undisturbed specimens and the correlation coefficients between cyclic liquefaction resistance curves and test results were large than 0.89.The results supported that the initial shear wave velocity of loose saturated soils was a key parameter controlling its cyclic liquefaction resistance.
