Abstract
In this paper, an integrated numerical model is developed to investigate wave-seabed interactions around multiple submerged permeable breakwaters in an elasto-plastic seabed foundation with Bragg effects. In this model, the wave motion is governed by VARANS equation and the Biot’s u-p approximation is used to govern soil-pore fluid interactions in porous medium. The advanced elasto-plastic constitutive model (PZIII) is used to reproduce the plastic soil behaviour in seabed foundation under long-term cyclic wave loading. Numerical results show that the wave motion can be largely changed due to Bragg effects. Under the strongest Bragg effect, the soil permeability and degree of saturation can significantly affect the liquefaction potential in seabed foundation.
