摘    要:波浪经过透水结构的传播是波波相互作用非线性的过程,难以用数学模型进行准确模拟。针对这一复杂问题,选取了矩形、梯形、三角形、半圆形4种结构形式的潜堤,采用波浪断面物理模型试验的方法对这4种结构形式潜堤的消浪特性进行了研究。选取常用的影响因子,分析4种潜堤在波浪作用下透射系数随影响因子的变化规律,并通过经验公式对试验结果进行验证。研究结果表明潜堤消浪性能受入射波浪要素、潜堤相对堤顶水深、潜堤自身尺寸等因素影响较大。

关 键 词:潜堤;透射系数;波浪物模试验

Abstract:The propagation of waves through permeable structures is a non-linear process of wave-wave interactions,which is difficult to accurately simulate with mathematical models.In view of this problem,four types of submerged breakwaters,rectangular,trapezoid,triangle and semicircle,are selected to study the wave resistance performance of these four types of submerged breakwaters by wave section physical model test.The commonly used influencing factors are selected,and the variation law of the transmission coefficient under the action of the waves with these influencing factors is analyzed.The experimental results are verified by empirical formulas.The results show that the wave resistance performance of submerged breakwaters is greatly affected by factors such as incident wave factors,the water depth above the submerged breakwaters and the size of the submerged breakwaters.
Keywords:submerged breakwater  transmission coefficient  wave physical model test
