Deformation Analysis of Partially Saturated Soil in Slopes
Anisotropic visco-plastic constitutive model and generalized pore pressure are incorporated in the equation between irreversible downwards velocity and visco-plastic strain rate. The solution to velocity is obtained and by use of it the progressively destructurated deformation of partially saturated natural soil in slopes is analyzed to investigate the influence of anisotropy, viscosity, degrees of structure and destructuration, and partial saturation. The solutions are verified by use of the observed field behavior of a natural slope.
