| 摘 要： | 对于在过水土石坝上设置圆弧曲线堰后的过流能力进行了试验研究,根据几组圆弧曲线堰过流能力的比较,初步分析了圆弧曲线堰的流量系数变化规律及圆弧半径等对其的影响。试验结果表明圆弧曲线堰相对于梯形堰有着更大的流量系数。同时,圆弧曲线堰的流量系数随圆弧半径R值的减小而增大,上下游坡度较陡的圆弧曲线堰具有较大的流量系数。

| Abstract: | The hydraulic experiment for flowing ability of arc weir was conducted to use the over-flow earth-rock dam,comparing with a series of test results.This paper analyzed the law of coefficient of discharge and the radius facts on arc weir.The results show that the arc weir's coefficient of discharge is higher than the broad weir's,meanwhile,the arc weir's coefficient of discharge become larger while the radius decrease,the arc weir with more sharp slope has higher coefficient of discharge. |

| Keywords: | over-flow earth-rock dam arc weir coefficient of discharge |
