摘要

建立了水力学实验模型，分析了平闸的自由流出流量。通过计算可以得到平闸自由流量系数的实验数据。将常用的三种不同的自由流量系数经验公式计算的实验数据与计算值进行了比较，为工程应用计算公式的选择提供了实验依据。通过曲线拟合的方法，提出了一种基于二次函数的自由流量系数的计算方法，为流量计算提供了新的参考。

Experimental Research of Flow Coefficient for Free Outflow of the Flat Sluice

We set up an experimental model of hydraulics, and analyze the free outflow flow of flat sluice. One can obtain the experimental data of the flat sluice freedom flow coefficient by calculation. In comparison with the experimental data and calculated values which is calculated by three commonly different kinds of freedom flow coefficient empirical formula, which can provide an experimental basis for the select of calculating formula of engineering applications. By curve fitting method, one proposed calculation method of free flow coefficient based on a quadratic function, which can provide a new reference for the flow calculation.
