An experimental study was carried out to investigate the tsunami surge impacts on small balls climbing on different slopes. Dam-break flows were generated in a flume to simulate tsunami surge. The water surface profiles at the sluice gate were observed, the tsunami inundation height and the surge velocity in the flume were measured, and the maximum climbing heights of small balls on different slopes were recorded. Results show that the dam-break speed and the tsunami surge strength increase with increasing reservoir water level. The increasing tsunami inundation height, the decreasing ball density, and the decreasing ball diameter have positive effects on the maximum ball climbing height. Based on the normalized experimental data, equations for estimating the maximum ball climbing heights on different slopes were proposed as functions of the inundation height, the ball diameter, and the ball density. The calculated values from the equation are generally within [Formula: see text]% of the measured values in the experimental ranges.

破坝式海啸对不同坡度小球攀爬影响的实验研究

进行了一项实验研究，以研究海啸对在不同斜坡上攀爬的小球的影响。在水槽中生成溃坝流以模拟海啸潮。观测了闸门水面剖面，测量了海啸淹没高度和水槽内涌流速度，记录了小球在不同坡度上的最大爬升高度。结果表明，随着水库水位的增加，溃坝速度和海啸强度增加。海啸淹没高度的增加、球密度的降低和球直径的减小对球的最大爬升高度有积极影响。基于归一化的实验数据，提出了估算不同坡度上最大球爬升高度的方程，作为淹没高度、球直径和球密度的函数。由公式计算得出的值通常在实验范围内测量值的 [公式：见正文]% 范围内。
