摘要
选取叶榭塘水闸2022年7—8月的实测数据,根据闸门开度及闸前水头的变化,其出流状态可分为淹没孔流和淹没堰流。利用传统水力学法、量纲分析法对过闸流量进行计算,通过修正流量系数,得出叶榭塘水闸最佳的过闸流量计算方法及公式。研究分析建议堰流状态(当e/H>0.65)的过闸流量采用修正系数后的传统水力学公式,而孔流状态(当e/H≤0.65)采用量纲分析法,所推求的公式也可用于推求过闸总水量。
Using measured data from July to August 2022 at the Yexietang Sluice,the flow conditions were categorized into submerged orifice flow and submerged weir flow based on gate opening and upstream water head variations.Flow through the sluice was calculated using traditional hydraulic methods and dimensional analysis,with adjustments to the flow coefficient.The study determined the optimal flow calculation method and formula for the Yexietang Sluice.The analysis recommends using the traditional hydraulic formula with a corrected coefficient for weir flow conditions(when<0.65)and dimensional analysis for orifice flow conditions(when>0.65).The derived formulas can also be applied to estimate the total discharge through the sluice.
