Random Wave-Induced Seabed Responses around Breakwater Heads

Abstract

Wave-induced pore pressures and effective stresses in a porous seabed around breakwater heads have been recognised as one of the key factors in the design of breakwaters. Unlike previous investigations, which were limited to regular wave loading, this paper investigated random wave-induced seabed responses. Two common wave spectra, B-M and JONSWAP, were used for the simulation of random waves in a model. Based on this poro-elastoplastic model, the influence of random wave parameters, waves and seabed parameters on the pore pressures around breakwater heads were examined and discussed in detail.
