摘要
本文在陈飞勇、苏鲁平研究的基础上,提出了梯形明渠临界水深的直接计算公式及合理迭代系数。用该式直接计算,或进行一次迭代,很大范围内临界水深的相对误差都接近于零,仅局部很小范围内的最大相对误差为5.9‰。
Based on the study results obtained by Chen Feiyong and shu Luping,this paper presents aformula for calculating critical depth of open-channel flow with trapezoidal cross-section and a rationaliteration factor.As the formula is used for direct calculation or a iteration is conducted,the maximumerror is less than5.9‰.
