Abstract

In this paper an Intrinsic Compressibility Framework for anisotropic clayey soils (Belokas and Kavvadas 2011), is extended, to account for the effect of partial saturation, leading to a complete volumetric compression framework for anisotropic, unsaturated clayey soils. The proposed framework incorporates compression curves that depend on both suction and degree of saturation to capture the bonding effect of inter-particle forces formed when degree of saturation drops below unity. It can reproduce: a) compression lines that depend on the level of stress induced anisotropy, b) unique compression lines for saturated materials irrespectively of the level of the applied suction, c) a continuously increasing post yield compressibility for soils compressed under constant suction, and lastly d) a maximum of collapse.
