The paper deals with a computational stochastic approach for the unilateral
contact problem of dynamic soil-pile interaction. Unilateral contact effects due to
tensionless soil capacity, soil elastoplastic-fracturing behaviour and gapping are strictly
taken into account, as well as environmental effects under uncertainty decreasing the soil
resistance. The proposed methodology concerns the treatment of both, the deterministic and
the probabilistic problem. The numerical approach concerning the deterministic problem is
based on a double discretization, in space by the Finite Element Method combined with
Boundary Element Method, and in time, and on nonconvex optimization. Uncertainties
concerning the input parameter values are treated by the Monte Carlo method in the
probabilistic problem section. Finally, the proposed methodology is applied for a practical
case of dynamic soil-pile interaction.
