    Abstract

    We investigate the mechanical instability of soil and subsequent destabilization of the ground resulting from internal erosion.We aim to throwlight upon the processes of seepage failure and ground depression from the particle (micro) level to the soil system (macro) level as a boundary value problem using DEM and continuum modelling and Smoothed Particle Hydrodynamics (SPH). Simulations of local seepage failure and internal erosion show the success of this micromechanics approach. From simulation results, when no internal erosion has occurred and the leaked water was clean, the toe slope of the levee becomes swollen and loose, but the levee did not result in a break. When internal erosion has occurred and the leaked water was muddy, then local deformation of the toe slope progresses, and the levee became instable and collapsed.
