Abstract

Previous studies have shown that desaturation can improve the liquefaction resistance of originally saturated sand. To apply this method in practice, we need to establish the relationship between undrained liquefaction resistance and the degree of saturation for sand. In this paper, previous studies on the undrained strength and liquefaction behavior of partly saturated sand are reviewed first. Then, experimental results of triaxial undrained compression and extension tests on loose sands are presented. The data are used to examine the relationships between undrained liquefaction resistance and degree of saturation of samples under different loading modes.
