| 摘 要： | 针对目前突扩式水跃跃长及跃后水深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,依据现有突扩式水跃试验实测数据成果,在对相关参数曲线特性全面分析的基础上,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、适用范围广的简化计算公式。精度分析表明,该公式求解水跃及跃后水深的最大相对误差分别为9.75%和8.84%,均小于现有公式的计算误差。

Simplified Calculation Method of the Longth and Water Depth of Sudden Enlarged Hydraulic Jump |
| |
| Abstract: | Focusing on issues like very complex calculation process ,low accuracy ,limited applicability etc .,this paper proposed a simplified method to calculate the length and water depth of sudden enlarged hydraulic jump based on the ex -perimental data ,which adopt the relevant parameters curve characteristics ,the optimal fitting technology ,through the fit-ting of multiple sets of optional function approximation .The calculation process is simple and applicable range is relative-ly wide .The accuracy analysis shows that the maximum relative error of the formula is 9 .75% and 8 .84% respectively , which is lower than the current calculation formula . |
