海水導入を目的とした潜堤付防波堤の開発(2) Development of the Breakwater with remote submerged Rubble Mound for the purpose of Interchanging Sea Water (II) 波力の検討 Investigation on Wave Pressure Nakaizumi, Masamitsu 中泉, 昌光 ナカイズミ, マサミツ Nakaizumi 中泉 ナカイズミ Masamitsu 昌光 マサミツ Manabe, Motobumi 間辺, 本文 マナベ, モトブミ Manabe 間辺 マナベ Motobumi 本文 モトブミ Yamamoto, Masaaki 山本, 正昭 ヤマモト, マサアキ Yamamoto 山本 ヤマモト Masaaki 正昭 マサアキ metadata only access This report shows the experimental study on the wave pressure exerted on the breakwater with the remote submerged rubble mound and denotes a formula for estimating the wave pressure. Through this experimental study, it was proved that the wave pressure exerted on the upright section of the breakwater was influenced by the depth above the submerged mound, hc, and the distance from the front of the upright section to the top berm of the submerged mound, l'. Therefore, enough distance and an appropriate height of the submerged mound must be determined to expect the wave pressure reduction. To be concrete, l' most be more than 0.2~0.25L (L: wave length) in the case of hc = 0~0.25h (h: water depth), and the distance more than 0.48L is necessary in case htat hc is equal to 0.5h. The wave pressure acting on such a breakwater is calculated by the coefficient for estimating the reduction rate of wave pressure. 水産工学研究所 National Research Institute of Fisheries Engineering 1988-03 jpn article https://fra.repo.nii.ac.jp/records/2008084 nrife_gd_10_57 https://agriknowledge.affrc.go.jp/RN/2010392142 日本農学文献記事索引(agriknowledge) AN00329681 0389-2344 水産工学研究所技報. 水産土木 Technical report of National Research Institute of Fisheries Engineering.
