摘要
在现有的矩形方箱和透空结构的基础上,提出一种由立管和水平板组合而成的消浪结构。利用波浪水槽物理模型试验,测试该结构在单向规则波作用下的消浪性能。分别探讨了其单排布置和双排布置时的透射系数随结构宽度、相对吃水深度、相对间距等因素的变化规律。结果表明:单排布置时,透射系数随结构宽度的增大而减小,总体上随吃水深度的增大而减小;双排布置时,透射系数相对总宽度相同的单体结构减少10%,透射系数随吃水深度的增大而减小,前后间距对透射系数的影响不明显。对试验结果数据进行曲线拟合,得到了透射系数关于各影响因素的函数表达式。
Based on the existing rectangular structures and permeable structures, a kind of wave attenuation structure composed of vertical pipes and horizontal plates is proposed. Through the model tests in wave flume, the wave attenuation performance of the structures is tested under the action of unidirectional regular waves. The variation of the transmission coefficient with structure width, relative draft and relative space was are discussed. The results show that the transmission coefficient decreases with the increase of structure width and decreases with the increase of the relative draft in general when it’s laid out separately. For the double-row layout, the transmission coefficient decreases by 10 % compared with the single-row layout with the same total width. The transmission coefficient decreases with the increase of relative draft. The influence of the distance between two structures on the transmission coefficient is not obvious. The function expression of the transmission coefficient on each influencing factor is obtained by curve fitting of the experimental data.
