中文摘要：

温和斜坡方程(MSE ) 和边界 ElementMethod (BEM ) 的一个线性混合模型被开发在沿海的地区在漂浮的结构附近学习波浪繁殖。两个都，在由漂浮的结构的地形学和波浪衍射的影响下面的波浪折射被考虑。因此，模型在任意的形状而且波浪的沿海的漂浮结构附近提供波浪性质力量在上和结构的水动力学特征。不同途径与相比表明现在的混合模型的有效性。几数字测试在不同情形下面为浮桥的盒子被执行。漂浮的水动力学特征上的地形学的影响在沿海的区域组织的结果表演是重要的并且不能在大多数被忽略有实际兴趣的波浪时期范围。

英文摘要：

A linear hybrid model of Mild Slope Equation （MSE） and Boundary Element Method （BEM） is developed to study the wave propagation around floating structures in coastal zones. Both the wave refraction under the influence of topography and the wave diffraction by floating structures are considered. Hence, the model provides wave properties around the coastal floating structures of arbitrary shape but also the wave forces on and the hydrodynamic characteristics of the structures. Different approaches are compared to demonstrate the validity of the present hybrid model. Several numerical tests are carried out for the cases of pontoons under different circumstances. The results show that the influence of topography on the hydrodynamic characteristics of floating structures in coastal regions is important and must not be ignored in the most wave period range with practical interests.
