| 作为防浪建筑物的密排大圆筒透空防波堤因其具有较好的透水性和对生态环境影响较小的优势，在港口、海岸及近海工程中有广阔的应用前景。通过对密排大圆筒防波堤结构进行波浪物理试验，初步分析了不同筒径、不同筒间距密排大圆筒的透反射性能，主要分析了不同波陡、不同相对间距和不同相对筒径的密排大圆筒在不同波高、波长入射波浪下的消浪性能，比较了密排大圆筒结构与密排桩结构的透浪性能的区别。试验结果表明：密排大圆筒防波堤的透射系数随筒径和波陡的增大而减小，随筒间距的增大而增大；当相对间距接近时，较大筒径密排大圆筒结构对波浪的消浪效果更显著；密排桩对相对间距的变化更为敏感，而密排大圆筒结构在较大相对间距时仍然能有效阻挡部分波浪的透射。根据试验结果得到了密排大圆筒防波堤透射系数的拟合公式，并利用独立的试验数据集对其准确性进行了检验，检验结果显示良好。 |

| As a wave protection structure, the closely spaced large-diameter cylinder permeable breakwater has broad application prospects in port, coastal, and offshore engineering due to its advantages of high water permeability and minimal impact on the ecological environment. In this paper, physical wave experiments were conducted on the closely spaced large-diameter cylinder breakwater to preliminarily analyze the wave transmission and reflection performance of cylinders with different diameters and spacings. The wave dissipation performance of closely spaced large-diameter cylinders under varying wave steepness, relative spacings, and relative diameters, and for incident waves of different wave heights and wavelengths, was mainly investigated. The differences in wave transmission performance between the closely spaced large-diameter cylinder structure and a closely spaced pile structure were also compared. The experimental results show that the transmission coefficient of the closely spaced large-diameter cylinder breakwater decreases with increasing cylinder diameter and wave steepness, but increases with larger cylinder spacing. When the relative spacing is close, structures with larger-diameter cylinders exhibit more significant wave dissipation effects. Closely spaced piles are more sensitive to changes in relative spacing, whereas the closely spaced large-diameter cylinder structure can still effectively block partial wave transmission even at larger relative spacing. Based on the experimental results, a fitting formula for the transmission coefficient of the closely spaced large-diameter cylinder breakwater was developed and its accuracy validated using an independent experimental dataset, showing good agreement. |
