Effect of Loading Frequency on the Liquefaction Resistance of Poorly Graded Sand

초록

Cyclic simple shear tests were carried out to study the effect of frequency (f) on the poorly graded sand's liquefaction resistance. The samples are prepared in the medium state (D-r = 60%) by the deposition method, and a wide range of f (f = 0.03, 0.05, 0.1, 0.2, and 0.5 Hz) is considered. The results show that the liquefaction resistance is uninfluenced by low f (0.03 and 0.05 Hz). When the f is higher than the optimum frequency (f(opt) = 0.1 Hz), the liquefaction resistance increases with increasing f.
