摘要
用实验研究方法 ,对作用于直立圆柱上的破碎波浪力进行了研究。实验在造波水槽中进行 ,破碎波通过可调式倾斜池底实现。实验分破碎波压力分布测定和破碎波总力测定两部分。实验结果表明 ,破碎波压力沿深度呈指数规律变化 ,但水面上下规律不同。将实验研究与理论分析相结合 ,应用曲线拟合技术 ,得出了破碎波压力的分布规律 ,给出了应用压力积分法计算破碎波浪力的估算公式。与实测的破碎波总力相比 ,均方根破碎波浪力的估算结果具有较高的置信度 ,建议在工程中应用。
The breaking wave forces on vertical cylinders in shallow water were studied by means of experimental methods. The experiments were carried out in a wave channel. The breaking waves were simulated using an adjustable inclined seabed. The pressue distribution and total wave forces were measured. The results indicate that the breaking wave pressures are distributed exponentially in vertical direction, with different law below and above the still water level. Combining the experimental data and theoretical analysis, the distribution law of breaking wave pressures was given using the curve fitting technology. An experimental formula was given to estimate the breaking wave forces on vertical cylinders. Compared with the test data, the estimated root mean square breaking wave forces have higher reliability and is recommended for engineering application.
