摘　　要：采用FUNWAVE-GPU模型对典型潜堤和缓坡地形上海浪的非线性传播变形进行了数值模拟。与实测数据的对比结果表明,该模型可以较好地模拟近岸复杂地形上海浪的反射、折射和绕射等现象,空间步长对数值模拟效果具有较大影响,GPU并行加速技术有效提高了模型的计算效率。In this paper,the FUNWAVE-GPU model is used to simulate the nonlinear propagation deformation of coastal waves on typical submerged bars and mild slope.The comparison with the measured data shows that the model can correctly simulate the reflection,refraction and diffraction of waves on the nearshore complex terrain.The spatial step has a great influence on the numerical simulation result.The GPU parallel acceleration technology can improve the computational efficiency of the model effectively.
