Abstract

The stability of layered seabed subjected to combined wave and current loading was studied by numerical model based on Biot's consolidation theory. The numerical results reveal that the existence of following current not only aggravates the possibility of liquefaction, but also increases the depth of shear failure. As a treatment, higher permeable soils layered upon seabed composed of low permeable soil will decrease the potential possibility of liquefaction as well as help to prevent original seabed from shear failure.
