Title: Wave-induced Pore Pressure in Sandy Seabed near Vertical Breakwater of Rubble Mound
Abstract: The interaction between wave,seabed and breakwater is important in coastal engineering.Many coastal structures have been damaged by the wave-induced seabed response.We will examine the issue of wave-seabedrubble mound vertical breakwater interaction through flume test.Based on the experiment result,the wave induced pore pressure around a vertical breakwater will be examined through a parametric analysis.It shows that pore water pressure increases with the increment of wave height and period,decreases with the depth of water.Permeability and thickness of sand bed are the most important factors influencing the pore-water pressure;and the pore-water pressure around breakwater are increased after its building.Effective stress is reduced,and it causes serious influence on the stability of the breakwater.Simultaneously,the experiment shows that it is reasonable to study wave induced pore pressure in sandy seabed based on Biot's poro-elastic theory.
