| 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. |
