WAVE ELIMINATION STRUCTURE
To provide a wave elimination structure which is arranged on an in-port side of a breakwater structure and can sufficiently reduce reflectivity of long-period waves generated in a port even with the reduced size.SOLUTION: A wave elimination structure 1 that is arranged on an in-port side of a breakwater structure 100 and can reduce reflectivity of long-period waves X generated in a port is composed of: a mound 10 which has an upper surface 11 with a predetermined length from the wave elimination structure 100 to a shore offing direction L and whose cross-sectional shape having an inclined surface 12 gradually inclined to the side of a sea bottom 110 from the tip of the upper surface 11 as progressing toward the shore offing direction L is a one-sided inclined trapezoidal shape; and a covering material 20 which covers the upper surface 11 of the mound 10. A top end face 20a of the covering material 20 is formed with a height within a range of ±1 m of an average tide level of a sea water surface, and the covering material 20 has a center opening 22 recessed from the top end face 20a toward the mound 10.SELECTED DRAWING: Figure 5
【課題】本発明は、防波構造物の港内側に配置され、さらに小型化しても港内に発生した長周期波の反射率を十分に低減することができる消波構造物を提供することを目的とする。【解決手段】防波構造物１００の港内側に配置され、港内に発生した長周期波Ｘの反射率を低減させる消波構造物１を、防波構造物１００から岸沖方向Ｌに向かう所定の長さの上面１１を有するとともに、上面１１の先端から岸沖方向Ｌに向かうに従って徐々に海底１１０側に傾斜する傾斜面１２を有する断面形状が片傾斜台形状となるマウンド１０と、マウンド１０の上面１１を覆う被覆材２０とで構成し、被覆材２０の天端面２０ａが、海水面の平均潮位に対して±１ｍの範囲内となる高さで形成され、被覆材２０は、天端面２０ａからマウンド１０に向かって凹状となる中央開口２２を設けた。【選択図】図５
