摘　　要：堰闸出现淹没式堰流时,水工建筑物法测流需要一定的水位差条件,水位差变小时,计算流量精度变差。基于淹没式堰流常见的堰闸流量计算公式,通过误差分析的方法推导出满足测流精度要求的水位差条件的计算公式,通过数量及分析给出满足测流精度要求的水位差条件的估算方法。When a submerged weir flow occurs in a dam,the hydraulic structure method requires a certain water level difference condition for flow measurement.As the water level difference decreases,the accuracy of flow calculation deteriorates.This article is based on the calculation formula for the common flow rate of submerged weir gates through error analysis,and provides an estimation method for the water level difference condition that meets the requirements of flow measurement accuracy through quantity and analysis.
