基于波浪水槽试验，对潜堤能否有效减少海啸岸滩冲刷问题开展研究。选取孤立波作为入射波，考虑不同潜堤位置和堤顶水深情况，同时选取没有修建潜堤时海啸岸滩变化试验结果进行对比分析。实验对波高、流速、地形变化以及孤立波的上爬、回落等全过程进行测量和记录。研究结果表明，潜堤的修建并不能有效减少海啸对岸滩的冲刷，仅能改变淤积沙坝的高度和位置，且会造成潜堤离岸侧局部略有淤积，向岸侧会出现明显的局部冲刷坑。潜堤位于水跃发生区域时，对减小岸滩淤积沙坝高度效果最为明显。保持堤顶水深不变，减小潜堤的离岸距离，对减少最大局部冲刷深度效果更为明显。

submerged breakwater and a scouring on the onshore side.The effect of reducing the deposi-tion sand bar could be obvious when the submerged breakwater located in the hydraulic j ump took place.The maximum local tsunami scour depth could decrease,as depth of sub-mergence kept and offshore distance of submerged breakwater decreased.
