Large deformation and failure simulations for geo-disasters using smoothed particle hydrodynamics method

Geo-disasters result in serious loss of life and property, and prediction and prevention of these disasters is of great importance. The smoothed particle hydrodynamics (SPH) method, a mesh-less hydrodynamics technique, was applied to the modeling of large deformation and post-failure behavior of geomaterials in geo-disasters with some success. The main aim of this paper is to provide a general view of SPH applications for solving a range of large deformation and failure problems, such as dam breaks, slope failure, soil liquefaction, seepage damage, dynamic erosion, underground explosions and rock breakage. Rather than attempting to cover every application found in the technical literature, this review selects some typical examples and describes them in detail.
