摘要

In this study examined is the wave interaction with a new modified perforated breakwater, consisting of a perforated front wall, a solid back wall and a wave absorb-ing chamber between them with a two-layer rock-filled core.The fluid domain is divided into three sub-domains accord-ing to the components of the breakwater. Then by means of the matched eigenfunction expansion method, an analytical solution is obtained to assess the hydrodynamic performance of the new structure. An approach based on a step approach method is introduced Io solve the complex dispersion equa-tions for water wave motions within two-layer porous media.Numerical results of the present model are compared with previous limiting cases. The effects of rock fill on the reflec-tion coefficient and the horizontal wave force are discussed.
