摘要
闸后扩散式消力池池深计算需联立求解高次方程,常规的数学方法不能直接获得。现有的图解法及试算法或是求解过程依赖图表精度差,或是计算过程繁琐工作效率低,而利用微机编程获解又不便基层工程技术人员应用。经对池深水力计算相关公式的整理变换,采用优化拟合的方法,完成了对无量纲求解方程的拟合替代,在工程实用参数范围内,获得了可直接完成扩散式消力池池深求解的简化计算公式,计算过程简捷直观、成果精度满足工程设计要求。为此,文章以实例加以论证。
To calculate the depth of diffusive stilling pool behind the gate needs to be simultaneous with high order equations, can＇t be gotten by the conventional mathematical method directly. The existing graphic method and trial method is low in accuracy due to depending on the figures and charts during the solution process, or low in working efficiency because complex calculation process, but solutions obtained by computer process are not convenient for technique personnel working in-sit to apply. Through regulation and transmission for the formulas relevant with pool depth hydraulic calculation, the optional fit method was adopted to replace the fit of dimensionless equation, within the scope of practical project parameters, the simplified calculation formulas to calculate directly the depth of diffusive stilling pool were gotten, the calculation process is simple and intuitive, the result accuracy may meet the engineering design demands. Therefore ,the paper demonstrates in example herein.
