The Application of an Unsaturated Soil Elastoplasticity Model in Dam-Reservior Coupling System

Abstract:

This paper summarized the research of an unsaturated soil elastoplastic model(BBM), then a revised elastoplastic incremental stiffness matrix for unsaturated soil is deduced,discrete the governing equation in space domain and time domain with Galerkin weighted residual method and Euler method,a nonlinear finite element program is developed for the analysis the water-mechanical coupling system of unsaturated soil.The constitutive model is used for a homogeneous dam’s FSI problem, and the seepage and deformation in dam’s distribution consistent with law.
