Evaluation of wave induced liquefaction potential

This paper presents a one dimensional FEM model and an approximate analytical solution to evaluate the liquefaction potential of sandy sea beds under wave loading. The analytical solution can predict pore pressures with reasonable accuracy, so long as the pore pressure ratio is under 0.70. Results of pore pressure developed in an homogeneous sandy sea bed are presented as a function of a new non-dimensional time factor. These can be used to make rapid preliminary analysis of liquefaction potential. In addition, remedial measures to counteract liquefaction are also evaluated.
