为研究张紧式浮式防波堤的水动力性能,采用二维物理模型试验方法,研究系泊缆锚泊倾角、系泊缆预张力以及浮箱相对宽度等因素,在规则波作用下对迎浪面动水压力、系泊缆拉力以及透射系数等水动力特征的影响规律。结果表明:随着锚泊倾角增加,迎浪面动水压力呈先增加后减小的趋势,系泊缆拉力呈先增加后轻微减小的趋势,透射系数则呈明显的减小趋势;随着系泊缆预张力增加,迎浪面动水压力、系泊缆拉力呈增加趋势,透射系数呈先减小后增加趋势;随着浮箱相对宽度增加,迎浪面动水压力、系泊缆拉力和透射系数均呈减小趋势。该结果可为张紧式锚泊单浮箱浮式防波堤的设计和安全性评估提供参考。

To investigate the hydrodynamic capabilities of the taut floating breakwater, a two-dimensional physical modelling experiment was performed to study the influencing laws of such hydrodynamic characteristics as the hydrodynamic pressure on the front surface of the box, tension of mooring line and transmission coefficient under regular waves, considering factors such as mooring angle, pre-tension of mooring line and relative width of the floating box. The results show that, with the increase of the mooring angle, the hydrodynamic pressure on the front surface of the box first increases and then decreases; the tension of mooring line first increases and then decreases slightly; and the transmission coefficient obviously decreases. As the pre-tension of the mooring line increases, the hydrodynamic pressure on the front surface of the box and the tension of the mooring line increase, and the transmission coefficient first decreases and then increases. As the relative width of the floating box increases, the hydrodynamic pressure on the box, tension of mooring line and transmission coefficient all show a decreasing trend. The results can provide a reference for the design and safety assessment of taut mooring single pontoon floating breakwaters.
