Abstract
About pile-supported wave absorbing breakwater having a horizontal slit, we confirmed that wave dissipation performance did not have the difference so far even if slit shapes were different. However, we have not been able to inspect it about the influence that slit specifications (shape, opening rate, position) give to local scouring properties enough. In this study, we confirmed that scouring in case of the horizontal slit structure grew big in comparison with vertical slit structure in breaking wave by a model experiment and guessed that the cause depended on synergy of the vortex of the perpendicular to have a horizontal axis in the retarding chamber and the vortex on the structure by numerical computation. In addition, in vertical slit structure, a slit opening rate greatly influences maximum scouring right under the pile, and a slit position influences the scouring of the lower slit wall.
