摘　　要：基于对透空码头结构物波浪上托力研究现状的分析,运用垂向二维CFD数值波浪水槽建立模拟规则波作用下水平板波浪上托力的数值模型。通过物理模型和数值模型所获波浪压力结果的对比分析,总结平板底部流场和测点压强的分布特点,探讨不同周期波浪的最大冲击压强随波浪相对超高变化的规律。试验结果表明,规则波作用下波浪上托力的数值模拟结果与物理模型试验结果基本相符。By analyzing the research achievements of wave uplift force on the open wharf structure,the numerical model of wave uplift force on a horizontal plate are made through simulating regular wave in a vertical 2D CFD wave tank.By comparing and analyzing the different wave pressures gained from the physical model and numerical model,it is summarized the distribution characteristics of the flow field and the measuring point pressure at the bottom of horizontal plate.It is also discussed the rule that the maximum impact pressures of different period waves are changed by the relative wave clearances.It is shown in the test that the numerical simulation result of wave uplift force under regular wave basically accords with the physical model test result.
