| 英文摘要 | Soil-water retention curve (SWRC) is a constitutive relation indispensable for analysis of fluid flow and moisture and stress distributions in unsaturated soils. Although the SWRC is traditionally formulated in the regime of positive matric suction, it is also relevant in the negative matric suction regime where pore water are pressurized. To date, no mathematical model is available for characterization of SWRC in both the positive and negative matric suction regimes. In this paper, the underlying mechanism for hydraulic hysteresis is analyzed especially in the regime of negative matric suction, and a novel SWRC scanning hysteresis model is developed for both the positive and negative matric suctions. To demonstrate the performance of the proposed model, the simulated results are compared with experimental data available in the literature, indicating that the new model can describe well the hydraulic hysteresis of unsaturated soils. The proposed model introduces only one parameter in order to describe the scanning hydraulic behavior and is general in the sense that the model can describe well the soil-water retention characteristics in both the positive and negative matric suction regimes.
