摘要
提出了垂直导桩锚固方箱-水平板式浮堤,通过实验室物理模型试验研究了规则波作用下浮堤模型的消浪性能和升沉运动响应.探讨了相对宽度、水平板层数、水平板与方箱间距等几何参数对浮堤消浪性能与浮堤升沉运动的影响及消浪性能与浮堤升沉运动的相关性.试验结果表明提出的方箱-水平板式浮堤的消浪性能好于单一方箱,在B/L(模型宽度与波长比)为0.2时,其透射系数比方箱模型透射系数减小约0.2,升沉高度比方箱模型升沉高度减小0.3倍入射波高.通过对透射系数的主要影响因素进行多元回归分析得到了透射系数的拟合公式.
A new kind of floating breakwater, vertical pile-restrained pontoon-plates floating breakwater is proposed. Laboratory physical model tests were performed to study the wave attenuation performance and heave motion response of different kinds of pontoon-plates models. Influence of model geometric parameters （relative pontoon width, plate width, number of plates, distance between bottom of pontoon and plate） in wave attenuation performance and heave motion response were discussed, as well as the relationship between the wave attenuation performance and heave motion response. The results indicate that the wave attenuation performance of the new structure is improved. Its transmission coefficient and heave motion height are reduced 0.2 and 0.3 Hi （Hi is incident wave height） respectively compared with those of pile-restrained pontoon floating breakwater model at B/L = 0.2. Furthermore, the fitting expression of transmission coefficient is obtained by multiple regression analysis.
