From the modern porous media theories, the coupled eld equations for the soil are derived from the general context of nite deformations. The elasto-plastic bounding surface constitutive model with damage evolution as a property of cohesive soil is proposed and described as incremental relations between the changes of e ective stress and strain of the soil. Large deformation problems in the structured immiscible mixtures with changing volume fraction are addressed via the Updated Lagrangian formulation. Finite element spatial discritization, time integration, implementation of the model and the iterative procedures for solving the nonlinear incremental formulation are described. From the nite element code developed as u-p-U form, based on the porous media theory and bounding surface plasticity, the pile-soil interactive behavior is simulated during pile driving, consolidation, and subsequent loading. The numerically simulated results are compared with high quality eld and experimental data.
