TSUNAMI PROTECTION BREAKWATER AND TSUNAMI ATTENUATION STRUCTURE
To improve stability against tsunami for a tsunami protection breakwater attenuating tsunami energy.SOLUTION: A tsunami protection breakwater 10 installed in a front sea area of land to be protected, extending over a sea surface from a ground 15 by being supported on the ground 15, is provided with: a skeleton structure 12 passing tsunami under the sea surface; and a plurality of oblique plates 14 fixed on the skeleton structure 12 with a space therebetween in a vertical direction above a height of the sea surface in such a manner its height increases from offshore sides toward ashore sides, wherein inflow parts 25 of the tsunami are formed between the oblique plates 14 vertically adjacent to each other at the offshore sides of the plurality of oblique plates 14. and a fall for dropping, to the sea surface, tsunami flowed obliquely upward toward the shore side on the oblique plates 14 is formed at the shore sides of the plurality of oblique plates 14.SELECTED DRAWING: Figure 2
【課題】津波のエネルギーを減衰させる津波防波堤において、津波に対する安定性を向上させる。【解決手段】防護対象の陸地の前面海域に設けられる津波防波堤10は、地盤15に支持されて地盤15から水面上に延びており、水面下において津波を通過させる骨組構造12と、水面より上側の高さにおいて上下方向に間隔を空けて骨組構造12に固定され、沖側から岸側に向かって高さが増すように傾斜した複数の傾斜板14とを備え、複数の傾斜板14の沖側では、上下に隣り合う傾斜板14の間に津波の流入部25が形成され、複数の傾斜板14の岸側では、傾斜板14上を岸側に向かって斜め上に流れた津波を海面に落下させる落差が形成されている。【選択図】図2
