Abstract: Large-scale model tests were carried out to study wave-induced seabed response under one-dimensional condition with particular attention given to cyclic liquefaction of the seabed. Influence of wave period, degree of saturation and permeability of sand bed on the transient pore pressure response within the model seabed under applied surface wave loading was studied. Displacements of a light object and a heavy object in the momentarily liquefied deposit were investigated under different wave periods and different amplitudes of wave loading. A simple and easy to use one-dimensional analytical model for the wave-induced seabed response analysis was developed. The validity of one-dimensional approach for cyclic liquefaction study of the seabed was demonstrated. A simple chart was developed in terms of two dimensionless parameters to determine the maximum depth of cyclic liquefaction under different combination of wave, pore fluid and soil properties.
