摘要:
U形渠道抛物线形无喉段量水槽、直壁式量水槽、圆底形量水槽具有与U形渠道自然衔接，不抬高底坎，过泥沙能力较强，工程量较小，量水精度较高的优点，是U形渠道量水的优化选择，对这3种量水槽在不同尺寸、底坡和糙率条件下的U形渠道的适应性、壅水高度、工程量及其量水精度等技术性能进行系统分析，表明抛物线形无喉段量水槽的适用面广、工程量小、壅水高度较低，量水精度与其它两种量水槽的量水精度相当，是一种高性能的多泥沙U形渠道量水装置。
Abstract:
The applicability, backwater height, cement volume, flow measuring precision of vertical wall, parabolic thin plate, circle weir for U-shaped channel flow measurement are analyzed. The results point out that the parabolic thin-plate weir for U-shaped channel flow measurement are analyzed. The result spoint out that the parabolic thin-plate weir has some advantages, such as extensive applicability, small backwater height, low cement volume, high measure precision for small U-shaped channel flow measurement.
