| 摘 要： | 针对目前三角形断面共轭水深(完全水跃情况下)求解公式存在的计算过程繁复、误差大、适用范围有限等问题,在对三角形断面共轭水深基本计算方程进行简化整理的基础上,以共轭水深曲线线型分析为基础,采用优化拟合技术,通过对多组备选函数的拟合逼近,获得了计算过程简捷、适用范围广的共轭水深简化计算公式。精度分析表明,该公式求解三角形断面水跃跃前、跃后水深的最大相对误差分别为0.168%和0.124%,高于目前现有其他计算公式。

| Abstract: | In view of the present solution formulas of conjugate water depth of triangle section of the great error in the process of heavy and complicated, and limited application scope, based on the simplified consolidation and the linear conjugate water depth curve analysis, the optimum fitting technology, through the fitting of multiple sets of optional function approximation, the calculation process is simple and applicable range of the simplified calculation formula. The accuracy analysis shows that the maximum relative error of the formula is 0.168% and 0.124% respectively, which is higher than the current calculation formula. |
