Abstract

In this paper, the characteristics of the development of effective stresses and pore water pressure in elastic or elasto-plastic seabed with time under a sequence of wave loading are studied by virtue of numerical finite element analyses. Compared with analytical solution for elastic problem, the numerical procedure proposed can deal with complicated situation of seabed and can predict residual pore pressure. For inelastic seabed, bounding-surface hypoplasticity model is employed to describe the nonlinear stress-strain relationship of sand under cyclic loading. The development pattern of pore pressure under undrained condition obtained from laboratory experiments is not necessary in the numerical simulation.

Dynamic Response of Seabed Under Wave-Induced Loading

San Diego, California

In this paper, the characteristics of the development of effective stresses and pore water pressure in elastic or elasto-plastic seabed with time under a sequence of wave loading are studied by virtue of numerical finite element analyses.

For inelastic seabed, bounding-surface hypoplasticity model is employed to describe the nonlinear stress-strain relationship of sand under cyclic loading.
