A 3D FEM model is proposed and verified with existing experimental data for simulating wave-induced transient and residual pore pressure responses around a pile foundation. The numerical results show that the residual pore pressure tends to be amplified at the bottom of the pile foundation; near it, this pressure increases and the amplitude of transient pore pressure decreases with the decrease of soil permeability. The wave nonlinearity affects both transient and residual pore pressures around the pile. The effect of the pile diameter on the oscillatory pore pressure is much more obvious than that on the buildup of pore pressure. The liquefaction zone around the pile is asymmetric; the maximum liquefaction depth appears at the back of the pile foundation.
