摘　　要：为估算淤沙对水力自控翻板闸门启门水位的影响,基于现有理论,考虑淤沙对翻板闸门的水平压力、竖向压力和附着力,对连杆滚轮式水力自控翻板闸门进行受力分析,推导出闸前有淤沙情况下水力自控翻板闸门的启门水位计算公式。并通过模型试验测量不同淤沙高度下的启门水位,与利用该公式计算的结果进行对比,证明该公式具有一定的可靠性,可以用于计算本试验模型闸前有淤沙情况下的启门水位,为实际工程中分析淤沙对水力自控翻板闸门启门水位的影响提供依据。In order to estimate the effect of silt sediment on the water level of a hydraulic automatic flap gate with silt sediments in front of the gate ,a calculation formula of water level was deduced by analyzing its force balance .In the formula ,the horizontal pres‐sure ,vertical pressure and adhesion of silt were taken into account .The water levels under different heights of silt was measured by model tests .The measured results were compared with the calculation results .It shows that the calculation formula is reliable when it is used to calculate the water level of the test model with silt in front of it .The research results will serve as a basis for analyzing the effect of silt sediment on opening water level of Hydraulic Automatic Flap Gate in the practical engineering .
