| 为深入理解极端波浪与倒圆角方形立柱相互作用的机理，基于物理模型试验，研究了聚焦波作用下倒圆角方形立柱的波浪爬升现象。通过控制聚焦波的波陡、周期、浪向和聚焦位置，深入分析了聚焦波参数对波浪爬升高度和倍数的影响。结果显示：在一定条件下波陡和波周期的增加会显著增强波浪与立柱的相互作用，增大立柱表面的波浪爬升；聚焦位置的改变对波浪爬升高度有显著影响，当聚焦位置位于立柱后表面时，波浪爬升高度达到最大，当远离立柱表面时，波浪爬升高度降低但出现第二波峰。采用散射参数kr（k为波数，r为立柱特征尺寸）和波陡Hp/λp（Hp和λp为聚焦波的波高和波长）作为无量纲参数进行拟合得到的经验公式，对倒圆角方形立柱最大波浪爬升高度的预报效果较好。 |

| To gain a deeper understanding of the interaction mechanism between extreme waves and rounded-square columns, this paper investigates wave run-up on such columns under focused waves through physical model experiments. By controlling wave steepness, period, direction, and focusing position, the study examines the influence of various parameters on the maximum wave run-up height and run-up ratio. The results indicate that, under certain conditions, increasing wave steepness and period significantly intensifies wave-column interaction, thereby enhancing run-up along the column surface. Moreover, variations in focusing position also exert a notable effect on run-up height. When the focusing position is located at the rear surface of the column, the run-up height reaches its maximum. Conversely, when the focusing position shifts away from the column surface, the run-up height decreases, though a secondary peak emerges. Furthermore, the empirical formula fitted using kr (where k represents the wave number, r denotes the characteristic dimension of the column) and the wave steepness Hp/λp (where Hp and λp are the wave height and wavelength of the focused wave, respectively) as dimensionless parameters shows excellent accuracy in predicting the maximum run-up height of rounded-square columns. |
