Abstract

Some influences of sand fraction on the hydraulic conductivity and compressibility were examined. The followings are derived as conclusions: if the sandy particles do not make a skeletal structure and each particle independents in the clay matrix, increasing sand fraction contribute to decrease the compressibility, but does not affect on the hydraulic conductivity, under the same overburden stress. In this study, some evidence of sandy skeletal structure was observed for the specimens, whose clay fraction (less than 0.005mm) and sand fraction (larger than 0.075mm) are smaller than 16% and larger than 70%, respectively.
