综合流量系数在拦河闸坝泄流能力分析中的应用

Application of Comprehensive Discharge Coefficient in Analysis of Discharge Capacity of Barrage Dam

针对陵城区拦河闸坝泄流能力分析问题,利用流量系数法,对陵城区某拦河闸工作门不同泄流状态进行分析,通过对2020年的相关历史数据进行计算,得到对应的M值和M1值,分析其与水位或闸门开度的关系,并研究对应工作状态下拦河闸泄流能力。结果显示,M值会随着上游水位的升高而增大,M1会随着闸门开度的增大而增大。相较于设计1和设计2,研究方法可有效分析拦河闸泄流能力,其绝对误差最小为2.03%。研究结果可为今后水库的合理调度提供参考与借鉴。

In the face of the analysis of the discharge capacity of the barrage dam in Lingcheng district,the paper uses the flow coefficient method to analyze the different discharge conditions of a barrage gate in Lingcheng district,calculates the relevant historical data in 2020,obtains the corresponding values and values,analyzes the relationship between the values and the water level or gate opening,and studies the discharge capacity of the barrage gate under the corresponding working conditions.The results show that the value will increase with the increase of upstream water level and gate opening.Compared with Design 1 and Design 2,the research method can effectively analyze the discharge capacity of the river gate,with the minimum absolute error of 2.03%.The research method can make the reservoir operation more reasonable in the future.
