| 摘 要： | 基于Delft3D软件建立了北戴河中海滩浴场海域的二维及三维潮流和波浪耦合数学模型,并用实测潮流和波浪资料进行模型验证.利用验证后的模型模拟人工水下沙坝引起的水动力环境变化.结果表明:由于工程海域附近的潮流作用较弱,因此潮流影响仅体现在沙坝周围;4座人工水下沙坝具有一定的消浪作用,并且消浪作用随入射波高的增加而增强;总体上看,人工水下沙坝的建造使浴场附近的水动力作用减弱,水动力环境朝着有助于海滩保护的方向发展.

| Abstract: | A wave current coupling model was established based on Delft3D software for Zhonghaitan Beach coastal water and verified by tidal current and wave measurement data. Thus the hydrodynamic changes due to artificial sandbars were modeled and investigated by the verified model. The main conclusions can be drawn as follows: tidal current field only shows changes around the bars since the tidal effect is originally weak in the research area; four sandbars dissipate wave energy and dissipation function increases with incident waves; on the whole, the artificial sandbars reduce the effect of hydrodynamics and contribute to beach maintenance. |
