Abstract : this paper presents a new - type floating breakwater with the structure of “ duckweed ”. some circular wooden blocks were flexibly tied together and flat located on water surface. a series of experimental investigation were carried out. the experimental results show that 1 ) there are wave attenuation characteristics of the new - type floating breakwater ; 2 ) by comparing the two installation styles, the wave attenuation effectiveness anchored on the sea bed is better than that of anchored on the sea shore
文摘:模仿水生植物「浮漂」的結構形式，設計一種新形式的防波堤.將多塊圓形木板柔性連接成一體，平鋪於水面，對其進行了一系列的消浪效果的初步試驗研究.試驗結果表明，該結構具有消浪性能，並且其固定方式採用系泊於水下的消浪效果優于系泊于岸邊的This paper describes the application of semi - circular breakwater at home and abroad and the design innovation and optimization of semi - circular jetty in yangtze estuary deepwater channel regulation project, esp. the design of estuary jetty structure using semi - circular floating caissons ; a new calculation method for wave forces acting on the submerged semi - circular estuary jetty and the optimization design method for semi - circular structures are recommended
