Abstract

The porewater in unsaturated soil exists in three phases or components; the adsorbed water fixed on the surface of soil particles, the meniscus water surrounding contact points of soil particles and the bulk water occupying a part of space among soil skeletons and these water components influence on soil behavior in their own ways. This paper proposes a theoretical method for estimating the quantity of each component and quantifying their effects on soil behavior. The results of drained triaxial test on the specimens of various suction history were compared with the theoretically calculated values.
