| 摘 要： | 波浪在水深剧变地形上的传播，可以简化为波浪在台阶地形上的传播.利用二维数值波浪水槽可以很好地模拟这一过程，特别是对波浪在台阶上的非线性变形.数值计算结果与实验测量进行了比较，结果吻合良好.

| Abstract: | The propagation of waves passing over the abrupt changing topograghy can be simplified as a wave passing over a step.This flow process can be reasonably simulated by a 2\|D numerical wave flume developed in this paper,especially for the nonlinear transformation of the wave on the step.Numerical results have been verified by experimental data. |
| |
| Keywords: | numerical wave flume finite element method step topograghy boundary condition |
