Dynamic Liquefaction Properties of Sand-Clay Mixture
摘要
Abstract
Field observations and laboratory studies indicate that sand with a certain amount clay can be easily dynamically liquefied under certain conditions and that the amount of clay has a com-plex impact on the liquefaction resistance of sand.Using a CKC dynamic tri-axial test system,the liquefaction resistance of sand samples with different clay content (0%,5%,and 10%)was inves-tigated.The results show that the sand sample with 5% clay had the lowest liquefaction resist-ance;the generation of pore water pressure is obviously effected by the clay content.The liquefac-tion mechanism of the sand-clay mixture is explained according to the experimental results.关键词
