摘要
采用波浪物理模型和数学模型相结合的方式,研究了大型港口潜堤越浪后港内的波况。基于断面物理模型试验,测定了波浪在潜堤的堤前和越堤后的传播规律,通过数学模型研究了波浪传播到港内的波况。对天津临港工业区的港内波况进行了分析研究,分别对TK-2D的缓坡方程波浪数学模型和MIKE21的BW波浪模型的模拟结果进行对比,结果表明2种波浪数学模型均可模拟潜堤越浪对港内波高的影响,但对于潜堤越浪后次生波的衰减特性模拟均不够准确,有待于进一步研究。
The wave condition of large scale port with submerged breakwater was analyzed based on the combination of physical wave model and mathematical model.The wave transformation before and behind the submerged breakwater was studied by using sectional model test.According to the mathematical model,the wave conditions in harbor basin of Tianjin Harbor Industrial Zone were also studied.The wave height results of TK-2D wave model were compared with that of BW wave model.The results show that both TK-2D wave model and BW wave model can simulate the influence of overtopping on wave condition,but the regular of second wave transformation is not accurate,which needs further study.
