摘要:

【目的】明确直角堰在不同结构布置选型下的超泄特性与其大小关系。【方法】针对简化综合流量系数假设下，基本堰流关系模型率定中的短系列多元回归处理范式使用局限问题，由试验统计特征下的不同实测堰流精度率定结果发现了短系列因果映射关系中的实测堰流精度统计效应，进而建立了多维可变堰流特征变量模糊概率关联分布识别和实测堰流精度效应下的一致性响应机制。【结果】提出了实测堰流精度效应影响下的直角堰流计算方法。【结论】综合现有文献成果中不同短系列实测堰流精度样本的应用率定与验证表明，方法计算结果和试验统计结果一致性较好，研究成果可为类似工程的设计复核提供参考。

Abstract:

【Objective】Clarify the over discharge characteristics and size relationship of right angle weir under different structural layout and selection.【Method】Aiming at the limitation of the short series multiple regression processing paradigm in the calibration of the basic weir flow relationship model under the assumption of simplified comprehensive discharge coefficient, the statistical effect of the measured weir flow accuracy in the short series causal mapping relationship is found from the calibration results of different measured weir flow accuracy under the experimental statistical characteristics, Then, the consistent response mechanism under the effect of multi-dimensional variable weir flow characteristic variable fuzzy probability correlation distribution identification and measured weir flow accuracy is established. 【Results】A calculation method of right angle weir flow under the influence of measured weir flow accuracy effect is proposed. 【Conclusion】The application calibration and verification of different short series measured weir flow accuracy samples in the existing literature results show that the calculation results of the method are in good agreement with the experimental statistical results, and the research results can provide reference for the design review of similar projects.
