In conventional geotechnical engineering practices, soil is often assumed to be either in a dry or a fully saturated state. However, soil naturally exists in a three-phase unsaturated state, with characteristics that make the conventional design approaches conservative. Unsaturated soil behaviour is characterized by Soil Water Characteristics Curve (SWCC). It illustrates the relationship between gravimetric and volumetric water content and suction, with mechanisms like capillary and osmotic action influencing water distribution across saturation levels (Bilsel and Uygar, 2000). Consolidation in saturated soils is governed by dissipation of the excess pore-water. For unsaturated soils, SWCC is required to capture the complex compressibility behaviour. Of earliest models are that developed by Fredlund and Hasan (1965) which characterizes one-dimensional compressibility using coefficients for net normal stress and matric suction. More recently, Alibrahim and Uygar (2023) proposed a new model for SWCC. This study aims to evaluate the compressibility characteristics of unsaturated clays, accounting for these intrinsic relationships and mechanisms.
