Abstract

This contribution describes a preliminary parametric analysis of the factors affecting the pull-out resistance of screw-piles in undrained conditions. The numerical simulations rely on the Particle Finite Element method, a method known for its capabilities to tackle large deformations and rapid changing boundaries at large strains. A total stress analysis –assuming a quasi-incompressible elastic model along with a Tresca plastic model- is used to simulate the clayey soil behavior. Contact constraints are imposed to the solution with a penalty approach. As a first step, a two-dimensional geometry is used and the pile resistance to pullout and penetratoin is assessed.
