| 摘 要： | 对非线形波浪在透空式防波堤周围的波浪变形进行了数值模拟，在Boussinesq波浪方程中加入与透空建筑物有关的新的耗散项，从而界定了透空建筑物引起的部分反射和透射，波浪折射衍射的传播过程通过控制方程求解。波浪控制方程通过有限差分方法求解。模型应用于模拟波浪经过具有部分反射的群桩式透空结构，结果表明透空式防波堤可以有效地衰减波浪，是重力式结构的一种替代形式。

| Abstract: | The nonlinear wave transformation around wave-permeable breakwaters is simulated by solving Boussinesq-type equations including a new expression of dispersion term. Partial reflection-transmission and refraction-diffraction are numerically simulated by finite difference method and applied to engineering cases, such as wave transformation around wave permeable breakwaters with an array of piles. The study shows the wave permeable structures may reduce wave energy effectively and can be used as an alternative of heavy gravity structures. |
