ABSTRACT

A methodology for the 3D analysis of marine foundations is presented. The response in displacements, stresses and pore water pressures is obtained from a finite element coupled formulation implemented in the GeHoMadrid model. Loads due to wave action on the foundation are obtained from the IHFOAM model that solves the three-dimensional Reynolds Averaged Navier-Stokes (RANS) equations using a finite volume discretization and the volume of fluid (VOF) method. Additionally, the methodology includes a Generalized Plasticity based constitutive model for granular materials capable of representing liquefaction fenomena of sands subjected to cyclic loading, such as those frequently appearing in the problems studied. This methodology is applied to the study of the response of a caisson breakwater foundation.
