Abstract
The horizontal wave force acting on vertical walls of perforated caisson breakwater was experimentally investigated in this study. The maximum horizontal wave force acting on single and double chamber caisson was measured respectively and compared each other. By analyzing the obtained experimental data, it was clarified that the total horizontal wave force for double chamber caisson was 9% smaller on average than that for single chamber caisson when the total chamber width was the same for both caissons. The reason for such reduction of horizontal wave force on the double chamber caisson is found from additional dissipation of wave energy at the porous middle wall of the structure, by which rather impulsive wave force on the rear wall could be slightly diminished compared to the single chamber caisson.ompared each other.
