Abstract

A three-dimensional FEM model is proposed and verified with existing experimental data for simulating wave-induced transient and residual pore pressure responses in the soil around pile foundations. The numerical results show that the residual pore pressure tends to be amplified around the pile foundation, especially at the bottom of pile foundation. Parametric study indicates that the residual pore pressure in the vicinity of the pile foundation increases and the amplitude of transient pore pressure decreases with the decrease of soil permeability. The effect of pile diameter on the oscillatory pore pressure is much more obvious than that on the build-up of residual pore pressure.
