广州港出海航道三期工程潮流数学模型研究

用TK-2D软件建立了广州港深水航道所在海区的基于不规则三角形网格的潮流数学模型,在采用现场实测资料对模型进行充分验证的基础上,对伶仃洋深水航道进行了潮流数值模拟研究,从潮流场角度分析了深水航道开发的可行性。研究结果表明,深水航道方案实施后,整个伶仃洋流场基本不变,只是沿伶仃航道轴线附近,由于受航道开挖的影响,局部区域流速和流向略有变化,从潮流动力角度讲,伶仃航道是可以继续开挖的,广州港南沙港区深水航道三期工程是可行的。

Numerical modeling of tidal current on deepwater channel project of Nansha Harbor District of Guangzhou Port

By use of TK-2D software,2-D tidal current mathematical model with irregular triangular grids is set up in the sea area where deepwater channel of Nansha Harbor District of Guangzhou Port lies.On the basis of full validation and verification of the models with field data,the tidal current field is numerically simulated and studied on the deepwater channel project of Nansha Harbor District of Guangzhou Port.The development feasibility of deepwater channel is analyzed from the point of view of tidal current field.The study results show that the whole tidal current field in Lingdingyang Bay is basically unchanged except the slight change of local current velocity and direction near the Lingding channel axis affected by its excavation,and that the Lingding channel can be excavated further and the Phase III project of deepwater channel of Nansha Harbor District of Guangzhou Port is feasible from the point of view of tidal current force.
