Abstract

The soil-water characteristic curve (SWCC) is a crucial parameter for studying the movement of water in unsaturated soils. This study established three bulk densities (1.45, 1.55, and 1.65 g/cm3) to simulate tailings at different depths, utilizing the centrifuge method to determine their SWCCs and evaluate the applicability of various models. The results indicate that the water retention capacity of the tailings at a depth of 0 ~ 20 cm is the lowest, while that at 40 ~ 60 cm is the highest, with the 20 ~ 40 cm depth exhibiting intermediate retention capacity. Both the van Genuchten model and the Gardner model showed satisfactory fitting results; however, the Brooks-Corey model yielded residual water contents that were inconsistent with physical reality. In summary, the van Genuchten model demonstrated the highest fitting accuracy and is therefore suitable for modeling the SWCC of graphite tailings.
