This paper deals with large deformation finite element (LDFE) preliminary modelling of Full Displacement Pile (FDP) installation in cohesive soil deposit located in Jazowa, Poland. The detailed FDP auger geometry is applied and the drilling process is modelled with full 3D Coupled Eulerian-Lagrangian (CEL) formulation. The total stress approach and elastic-perfectly plastic model with rate-dependent Mises plasticity is used. The interaction between auger and surrounding soil is controlled by adhesive contact algorithm. The radial total stress distributions along FDP auger in selected distances from the pile axis are investigated. The reaction force and rotational moment which act on the auger are determined and the results of numerical analysis are compared with data registered by drilling rig. The aim of this paper is to clarify the installation effects which take place during FDP pile installation in soft cohesive soil.
