溢流堰的类型很多，各类堰的流量系数计算公式各异，各家所提出的流量系数计算公式，通常都根据水工模型试验成果。为验证这些成果应用于原体实际工程的符合程度，特收集了我国一些省水文部门提供的共３５处溢流堰的现场率定流量系数资料和部分实际工程的模型试验资料，其中宽顶堰２２处，高实用堰８处，低实用堰５处。应用这些资料与各家经验公式计算的流量系数进行了对比检验，凡与现场率定成果比较，误差在允许范围以内的现有经验公式，已大部为《水工建筑物测流规范》采用
There are many types of overflow weir, various types of weir flow coefficient calculation formula, each proposed flow coefficient calculation formula, usually based on hydraulic model test results. In order to verify the conformity of these achievements to the actual engineering of the original body, we collected the data of fixed-point flow rate and the actual experimental data of 35 weir weir provided by some provincial hydrological departments, 22, 8 practical high weir, low practical weir 5. Application of these data and each empirical formula to calculate the flow coefficient of the comparison test, where the rate of field results and the results compared to the error within the allowable range of existing empirical formula, most of the “Hydraulic Building Measurement Specifications” adopted
