建立了一个模拟开敞水域中航槽流场的平面二维数学模型．利用该模型计算得到的流速分布与袁美琦、李安中等人试验值相吻合，并计算了相当于天然情况下（各种水深、挖深比及航槽与水流的不同交角）的流场，得到了各种航槽与水流交角、不同挖深比的航槽流速折减系数变化规律图，及各种航槽与水流交角、不同挖深比的航槽中流向与航槽轴线交角的变化规律图，为开敞水域中航槽选线设计提供了依据。
A two-dimensional planar mathematical model is established to simulate the flow field of the navigation channel in an open water area. The flow velocity distribution calculated by this model is in good agreement with the experimental values of Yuan Mei- qi and Li Anzhong et al. The flow field corresponding to natural conditions (various water depths, depth-of-cut ratios and different angles of navigation slots and currents) The change rules of the reduction coefficient of the velocity of the flight channel at various angles between the navigation channel and the water flow and the different depth-of-depth ratio and the variation of the intersection angle between the navigation channel and the navigation channel Figure, for the open waters of navigation channel design provides the basis.
