Abstract

To simulate the effects of fines content on the liquefaction properties of sand, specimens of different fines content were prepared. Based on cyclic triaxial compression tests of these samples, the effects of fines content on the liquefaction properties were analyzed. Results show that for a constant value of dry density, the liquefaction resistance decreases with increasing fines content. Beyond the critical value of fines content of 30% the trend is reversed and the liquefaction resistance increases with increasing fines content. The results are consistent with the variation of relative density with increasing fines content, which verifies the effects of non-plastic fine-grained soils on liquefaction resistance of sandy soil reported by Polito et al.
