| 摘 要： | 从海啸波作用下岸滩演变、床沙组成变化、建筑物周围淘刷和数值模拟研究4个方面,总结分析了国内外的研究现状和最新进展,指出可控环境下的实验和数值模拟研究相对较少、床沙组成变化缺乏关注、建筑物周围局部冲刷机理认识不足、缺少多尺度数值模拟计算等是当前研究存在的主要不足。在特大型波浪水槽内开展实验研究、发展多尺度混合数学模型、完善海啸波作用下的泥沙输移计算理论等是未来研究取得突破的关键方向。

| Abstract: | Tsunami is one of the worst marine disasters. Coastal lowland areas can be seriously flooded as the result of high tsunami waves, which cause a significant threat to human life and property. High tsunami waves can move an extensive amount of coastal sediments and cause a significant change of beach profiles in flooded regions. This paper summarizes the status quo and advances in the study of tsunami waves from the perspective of beach profile evolution, sand grains sorting, scour around coastal structures and numerical simulation. In general, it has been a lack of experimental study and numerical simulation of tsunami impacts in a controllable manner. Specifically, it has been a lack of concern on sorting of sand grains by tsunami waves and insufficient understanding of the mechanism of scour around structures, as well as a lack of multi-scale numerical simulation. The experimental study in the giant wave flume, the development of multi-scale hybrid mathematical models and the improvement on the sediment transport computation theory should be the focus points in tsunami studies. This review study provides a useful reference for the future research. |
