崖门出海航道疏浚工程潮流泥沙变化数值模拟

Numerical Simulation of Tidal Current and Sediment for Dredging Project in Yamen Sea Channel

崖门出海航道穿越黄茅海,是连接银洲湖和珠海高栏港的重要通道。采用数学模型在对最近的水文数据和地形冲淤资料验证的基础上,对崖门出海航道的进一步浚深方案进行了潮流泥沙运动模拟和航槽回淤计算。计算结果表明:东航道水沙条件相对较优,泥沙回淤主要集中在拦门沙航段,具有进一步提升通航标准的空间,在同等条件下可选择优先开发东航道。

Yamen sea channel is the important sea-route connecting Yinzhou lake with Gaolan Port in Zhuhai city through Huangmao Sea. Based on the recent hydrologic data and the seabed change, a numerical model is used to simulate the movement of tidal current and sedimentation and to siltation in navigational channels to verify the advanced dredging plan for Yamen channel. The results show that there is some preponderance for the east channel in tidal current and sediment, and the sediment filling up is mostly in the mouth bars. Moreover, the eastern channel has the potential to improve the channel standard, which can be developed first when the conditions are the same.
