针对三汊河河口闸水流偏右侧的不利流态，为寻找改善水流流态的工程措施，采用大范围水深平均二维数学模型，对过闸水流流态进行了模拟研究。在难以改变现有地形的情况下，提出在闸前布置导流墙的工程措施，采用闸前左右岸流速比、水位差以及左右闸孔过流流量占比等参数作为改善效果的评价指标。结果表明，在合适墙长与墙体角度下，导流墙可起到明显的流态改善效果。

The flow passing Sanchahe sluice is deviated to the right side, causing unfavorable flow pattern, so engineering measures should be adopted to improve the flow pattern. With the establishment of a wide ranged 2D mathematical model of aver-age depth, the flow pattern was studied. It is difficult to change the existing topography, so a guide wall arranged at the front of the sluice is put forward. The parameters, such as the ratio of the flow velocity at left and right bank, water level difference and ratio of flow in right and left sluice outlet, are used as quantitative indicators to evaluate the improvement effects. The results show that with the reasonable length and angle, the guide wall can improve the flow pattern.
