    Abstract

    The evaluation of the wave-induced seabed response (including pore pressures and effective stresses) in marine sediment is a vital issue for coastal engineers involved in the design of foundation around marine structures. In this paper, the poro-elastoplastic model (PORO-WSSI II) is applied to investigate the wave-induced pore pressure in a porous layered seabed with different soil permeabilities. Unlike previous investigations, a three-dimensional case, around breakwater heads, is considered. Based on numerical examples, the following conclusions were drawn: (i) a significant difference of the wave-induced pore pressures and liquefaction between the previous poro-elastic model and the present poro-elastoplastic model is found; and (ii) an upper layer with larger permeability will reduce the liquefaction depth
