带柔性膜的浮式矩形箱透射性能试验研究

Experimental Study on Transmission Performance of Floating Rectangular Box with Flexible Membrane

为提高刚性矩形箱和柔性膜组合式浮式防波堤的消波性能,基于物理模型试验开展了不同规则波浪条件和模型几何参数下浮式防波堤透射性能研究.结果表明:在某一浸深下,浮式防波堤的透射性能随箱体相对宽度B/L的增大而减小;在所选择的试验参数内,浮式防波堤的透射系数随箱体宽度吃水比B/d和相对浸深d/L的增大而减小,随波陡H/L的减小呈下降趋势.

In order to improve the wave-absorbing performance of the rigid rectangular box and flexible membrane combined floating breakwater,the transmission performance of the floating breakwater under different regular wave conditions and model geometric parameters was studied based on the physical model test.The results show that at a certain immersion depth,the transmission performance of the floating breakwater decreases with the increase of the relative width B/L of the box.In the selected test parameters,the transmission coefficient of the floating breakwater decreases with the increase of the width-draft ratio B/d and the relative immersion depth d/L,and decreases with the decrease of the wave steepness H/L.
