Abstract

In this study, breaking-wave induced pore pressure response in a sandy seabed was numerically simulated by using the in-house OpenFOAM model. This paper introduces the application of a three-dimensional Finite Volume Method (FVM) model for fluid-seabed-structure interactions. First, the soil response induced by the action of breaking waves around a monopile is discussed, and then the potential of instantaneous seabed liquefaction near the pile foundation is further evaluated. Numerical examples demonstrate the free surface water elevation and the distribution of seabed liquefaction depth around piles are closely related to the hydrodynamic characteristics. Meanwhile, for the pile group system with various layouts, the hydrodynamic and dynamic seabed response characteristics are regarded as a function of pile group layout. This in turn will affect the development of the near-trapping and diffraction phenomenons.
