3次元数値波動水槽を用いた波力低減型海域制御構造物に関する数値実験

抄録

Experimental studies used to be conducted to investigate hydraulic performance of permeable breakwaters due to complexity of the wave absorption mechanism. Although the numerical wave flumes such as CADMAS-SURF have recently been applied to the wave-structure interaction system, 3-D configuration of permeable breakwaters cannot be reproduced by the method. In this study, CADMAS-SURF/3D which is newly developed as 3-D numerical wave tank is applied to estimate the hydraulic performance of the permeable breakwater. The applicability of CADMAS-SURF/3D to such structures is investigated from the comparison between experimental and numerical results, in which detailed wave dissipation mechanism is also discussed.
