INFLUENCE OF DRYING AND WETTING HISTORY AND PARTICLE SIZE ON STATE-DEPENDENT SOIL-WATER CHARACTERISTIC CURVES (SDSWCCS)
A state-dependent soil-water characteristic curve (SDSWCC) provides information of the water retention ability of an unsaturated soil by considering both the two stress state variables: soil suction and net stress. In this study, a modified volumetric pressure plate extractor was used to determine SDSWCC of a completely decomposed granite (CDG). Recompacted specimens were subjected to different stress states and different numbers of drying and wetting cycles. Effects of different particle size distributions on SDSWCC were also investigated.
