摘要
灌区的水费改革有利于我国节水制度的加强,这就需要推广一种切实、有效的量水设施,而U形渠道直壁式量水槽由于具有与U形渠道自然衔接,不抬高底坎,过沙能力较强,工程量较小,量水精度较高的优点,是U形渠道理想的优化选择。对U形渠道直壁式量水槽进行试验,并对实验数据进行分析,得出U形渠道直壁式量水槽的基本水力特性。
An irrigation district＇s water reform is beneficial to the strengthening of the water-saving system,which requires us to popularize practical,effective water facilities,while the U-shaped channel of straight wall tanks has the U-shaped channel due to a natural convergence,does not raise sills,has the advantages of high precision.They are ideal for optimization of U-shaped channel.This is the right U-shaped channel of straight wall tank testing,and analysis of experimental data obtained from U-shaped channels of straight wall tank＇s basic hydraulic characteristics.
