The Influence of Shell-Sand Mixing on the Dynamic Response of the Seabed Foundation in Front of a Slope Breakwater

Shell-sand mixing, as a novel technique for coastal protection and seabed improvement, holds broad application prospects. However, the underlying mechanism of its influence on the wave-induced dynamic response of the seabed beneath slope breakwaters remains unclear. In this study, physical model experiments were conducted in a wave flume to analyze the effects of shell-sand mixing on the amplitude of pore water pressure in front of the breakwater and the vertical attenuation coefficient of the seabed. The results indicate that the amplitude of pore water pressure decreased by up to 46.5% after the application of shell-sand mixing. As the mixing ratio of shell-sand increased, the vertical attenuation…
