The response of bearing pile with expanding end plate to tide level change was evaluated by FEM analysis in order to investigate a feasibility of pre-cast concrete bearing pile with expanding part to floating structure foundation. The end bearing pile was assumed to be an elastic solid, and the soil was assumed to be a fluid saturated poroelastic medium for some seabed grounds such as sand, silt and clay. The size effect of an end bearing plate at the tip of pile was numerically estimated for various seabed grounds. Simulation results imply that such end bearing pile has the effect on the dissipation of excess pore water pressure around pile.
