| 中文摘要: |
| 根据考虑流影响的缓坡方程，运用波动叠加原理，导出了一种适合大范围缓变地形情况下，不恒定非均匀流场中随机波的折绕射联合的数值模式。应用该模式进行了概化的半椭圆斜坡海底及渤海湾西部海域不恒定非均匀流场中随机波传播的折绕射联合的数值计算，获得了比较满意的结果。 |
| 英文摘要: |
| Based on the mild slope equation considering the influence of current and according to the wave motion accumulation principle, a refraction-diffraction combined numerical model for random wave in tidal unsteady non-uniform current, appropriate to the condition of mild topography in large scale, is derived. The model is applied to the numerical calculations of random wave propagation on a seabed with semi-ellipsis slant slope and in the western zone of the Bohai gulf. Satisfactory results are obtained. |
