The Research on the Impact of the Variability of Sluice Gateon the Discharge Capacity
In the drastic change rate movable-bed model test, it has been concerned about how to ensure similar discharge of the flood diversion gate. Six models with variable rates 1, 3, 5, 8, 10 and 13.3 separately have been chosen to compare their different discharges and to analyze the impact of the change rate on the discharge capacity. The results showed that: when their water heads were same, There were no obvious rules between the flow coefficients of the five distorted models and the variation rates, but when compared to the flow coefficient of the normal model, the former were on the higher side; when their water heads were different, the distorted models’ flow rate increased with the variation rate, and when the rate of change came to 5, the flow increasing value tended to stable and close to 20%.
