Simulation theory & method of 3D solid-liquid coupling

Based on the theory and mathematical model of coupling,the paper studies the simulation rule of 3D solid-liquid coupling based on the simulation theory.By testing the mechanics and seepage characteristics of the specimen,mainly the intension,permeability,separating water characteristic and so on,several typical simulation materials and their proportioning of containing water and deaden water layer are obtained.It provides the theoretical foundation and the material proportioning for the actual engineering in the field of 3D solid-liquid coupling in the future.At the same time the 3D simulation equipment and its testing system,which we developed are introduced.
