A numerical technique for modeling the soil as a two-phase medium by means of a user material subroutine is presented. The approach is applied to a classical FE analysis in a Lagrangian formulation using an explicit time integration rule and to a Coupled Eulerian-Lagrangian approach. The application of these two approaches to the problem of pile jacking into fully saturated soil under partially drained conditions is investigated and compared to the solution obtained by use of an iterative equation solver. The influence of the installation process as well as the influence of the permeability on the surrounding soil is investigated.
