应用J. S. MONTES提出的反堰流问题的数值解法，分析了水工模型试验中的尾水控制问题。提出了一套利用薄壁堰控制模型下游水位，使其自动满足给定的水位-流量关系曲线，并使出口段水流具有良好的自相似性的尾水控制方法。实际应用表明，该方法简单易行，效率高，具有实用价值。实测与原型的水位相对误差为2%～5%。

By applying the numerical method, presented by J. S. Montes, for solving inverse weir problems, this paper puts forward a method of designing control weir for hydraulic model in accordance with a given head-discharge equation almost automatically. The method may be applied to a hydraulic model test. The result of application shows that the method is efficient, simple and practicable. Relative errors of water level between model and prototype data equal 2%*.5%.
