搭建了一个水力学的实验模型，并对平板闸孔淹没出流的流量进行了实验，利用理论分析方法分析了平板闸门在淹没出流的流态下的流量计算公式，得出了淹没出流流量值主要与流量系数有关。为了对其流量系数进行研究分析，以常用的3种淹没出流流量系数的计算公式计算出流量，将计算得出的3种理论流量值分别与实验测得的流量值进行对比，得出了最优的计算方法，为工程应用中淹没流量系数计算公式的选择提供了实验依据。

This paper sets up an experimental model of hydraulics ,and tests the flow of the flat sluice submerged discharge. Theoretical analysis method is used to analyze the flow calculation formula of the bulkhead gate when the flat sluice of bulkhead gate is under the flow of submerged discharge. It is concluded that the submerged discharge flow value is mainly related to the flow coefficient. To study the flow coefficient of submerged discharge ,the flow is calculated using three different kinds of submerged discharge flow coefficient calculation formula. The three calculated theoretical flow value are compared with the experiment measured flow value to obtain the optimum calculation method ,which provides an experimental evidence for selecting the calculation formula of submerged discharge flow coefficient for the engineering application.
