摘要
该文介绍了海啸的成因以及海啸波的基本特征,总结了在数值模拟中经常用到的几种数值计算方法、控制方程以及各自的适用条件。分析了二维模型和三维模型的利弊,介绍了海底摩擦在近岸地区波浪传播和沉积物输移中所起的作用以及处理方法。旨在为进一步开展海啸数值研究提供理论上的参考和指导。
In this paper, the forming mechanism of tsunamis and the basic characteristics of tsunami waves are introduced. Some numerical calculation methods and governing equations commonly used in numerical simulation are summarized, accompanied with the respective application conditions. The advantages and disadvantages of two dimension and three dimension models were analyzed. Furthermore the important role that sea bottom friction plays on wave transformation and sediment transport in shallow water region was introduced. The purpose of this paper is to provide theoretical reference for the further numerical research on tsunami waves.
