    • Abstract
  • The prediction method for soil-water characteristic curve under different initial void ratios is the foundation of the study on hydro-mechanical coupling of unsaturated soils, so it is of important research significance. For this purpose, the prediction method for air-entry value of soils with different initial void ratios is established based on the fractal theory. The fractal dimension of different initial void ratios is studied and discovered to be approximately the same rule. On this basis, the prediction method for soil-water characteristic curve of soils with different initial ratios is established by using the fractal model. The experimental results show that the proposed prediction method is reasonable.
