Abstract
In this study, a new three-dimensional (3-D) model was developed to provide better understanding of the mechanism for wave-induced seabed response around mono-pile. Based on poro-elastic theory, the fully dynamic (FD) formulations were adopted in the present model to simulate pore water pressure, soil stresses, displacements of both soil and mono-pile. Good agreement between numerical simulation and experimental results was obtained. Based on parametric study, numerical results indicated: (1) wave diffraction and reflection have significant effects on pore water pressure and soil displacements around mono-pile; (2) the most sensitive position for seabed parameter to pore water pressure around mono-pile locates in front of mono-pile while the least sensitive position is at the position of angle 3π/4 with respect to the incident wave direction; and (3) the increase of mono-pile horizontal displacement corresponds to the increase of wave height and the decrease of seabed Young's modulus.
