摘要: 基于长序列潮位资料，使用MIKE21建立大范围二维潮流数学模型，以深圳小漠湾国际物流港口与华润电厂等大型工程为研究对象，研究人类活动影响下的小漠湾及附近海域水动力变化特征。研究表明，围填海工程致使小漠湾海域潮流场有不同程度的变化，流速方面大多呈现减小状态，流向方面有一定局部改变，但总体变化不大。基本上是越靠近工程区，潮流场变化越为明显。通过数值模型计算工程实施后工程区周边泥沙冲淤强度分布显示，受工程建设影响，在潮流作用下工程区附近海域均有不同程度的冲刷和淤积，最大淤积量在0.08 m，最大冲刷量在−0.18 m。
Abstract: Based on the long-series tide level data, a large-scale two-dimensional power flow mathematical model was established using MIKE21, and the hydrodynamic change characteristics of Xiaomowan and the surrounding sea areas under the influence of human activities were studied by taking large-scale projects such as Shenzhen Xiaomowan International Logistics Port and China Resources Power Plant as research objects. The results show that the tidal current field in Xiaomowan area has changed to varying degrees due to reclamation projects, and most of the current velocities have decreased, and the flow direction has changed locally, but the overall change is not large. Basically, the closer you get to the engineering area, the more obvious the change in the tidal force field. By using numerical models to calculate the distribution of sediment erosion and sedimentation intensity around the engineering area after implementation, it was found that due to the influence of engineering construction, the sea area near the engineering area has varying degrees of erosion and sedimentation under the action of tides. The maximum sedimentation amount is 0.08 m, and the maximum erosion amount is −0.18 m.
