Experimental Study on the Performance of Twin Plate Breakwater
Abstract:The wave transmission characteristics and wave induced pressures on twin plate breakwater are investigated experimentally in regular and random waves.A total of twenty pressure transducers are fixed on four surfaces of twin plate to measure the wave induced dynamic pressures.The spatial distribution of dynamic wave pressure is given along the surface of the twin plate.The uplift wave force obtained by integrating the hydrodynamic pressure along the structure is presented.Discussed are the influence of different incident wave parameters including the relative plate width B/L,relative wave height Hi/a and relative submergence depth s/a on the non-dimensional dynamic wave pressures and total wave forces.From the investigation,it is found that the optimum transmission coefficient,Ki occurs around B/L =0.41 ~ 0.43,and the twin plate breakwater is more effective in different water depths.The maximum of pressure ratio decreases from 1.8 to 1.1 when the relative submergence depth of top plate is increased from -0.8 to +0.8. 作者: Author: GUO Chuan-sheng ZHANG Ning-chuan LI Yan-yang LI Jing-bo FANG Zhuo CUI Cheng 作者單位: State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology, Dalian 116024, China 期 刊: 中國海洋工程(英文版) ISTICEISCI Journal: China Ocean Engineering 年,卷(期): 2011, 25(4) 分類號: U656.24 Keywords: twin plate wave pressure vertical wave force relative submergence transmission coefficient 機標分類號: TN TN9 機標關(guān)鍵詞: Performance dynamic wave pressure transmission characteristics transmission coefficient hydrodynamic pressure spatial distribution different pressure ratio investigation incident wave wave height the optimum wave force total depth structure influence effective decreases found 基金項目: the National Natural Science Foundation of China Experimental Study on the Performance of Twin Plate Breakwater[期刊論文] 中國海洋工程(英文版) --2011, 25(4)The wave transmission characteristics and wave induced pressures on twin plate breakwater are investigated experimentally in regular and random waves.A total of twenty pressure transducers are fixed on...【Experimental Study on the Performanc】相關(guān)文章:
