Modeling of Consolidation Considering Coupled Soil-Fluid Interaction
Expulsion of excess pore water pressure caused by load applied for longer time which results in reduction of volume of the soil is termed as consolidation of soil mass. The response in terms of displacement is dependent of soil mass properties, applied loading, pore water pressure, and time. The present paper includes formulation of consolidation problem using finite element method (FEM). The basic matrix equations for coupled finite element are formulated based on Biot’s consolidation equations, coupled with two-dimensional equilibrium equation and continuity equation. Shape function is used to discretize the spatial variables, and finite difference time marching scheme is used to discretize the time domain. The FORTRAN 90 program has been used for writing the FEM code. A parametric study has been also carried out for different elastic modulus to obtain the response of soil deposit.
