ABSTRACT
Seepage failure including flowage deformation and hydraulic fracture, plays an important role on damage of dike under flood, flow of ground caused by liquefaction and improvement of ground by injection and/or penetration procedures. These problems must be solved with interaction among three phases: solid (soil), liquid (water) and gas (air). Distinct analysis (e.g. DEM) is adapted to abruption, failure and flowage, but unsuitable procedure to analysis domain of large scale. Continuum analysis has opposite properties to that. In this paper, there is a new attempt to develop the procedure which fuses distinct and continuum analyses by “Smoothed Particle Hydrodynamics (SPH)” with account for the interaction among three phases.
