摘要: Summary The paper presents the finite volume formulation and numerical solution of strain one-dimensional consolidation equation. The equation used in this study utilises a nonlinear continuum representation with varying compressibility hydraulic conductivity thus inherits material geometric nonlinearity. Time-marching explicit scheme has been to achieve transient solutions. terms have evaluated known previous time step value independent variable, that is, void ratio. Three-point quadratic interpolation function Lagrangian family evaluate face values at discrete control volumes. It shown is stable convergent for general practical cases consolidation. Performance by comparing results an analytical piecewise piecewise-linear difference model. approach seems work well offers excellent potential simulating Further, parametric performed on soft organic clays, influence various parameters ate characteristics soil shown.
