摘　　要：计算消力池深需联立求解高次方程,常规的数学方法不能直接获得。目前的试算法、迭代法及近似算法计算繁琐、精度不高,而智能算法又不便基层人员应用。通过对池深水力计算相关方程式的整理变换,获得了无量纲求解方程,采用优化拟合的方法,通过对无量纲求解方程的拟合替代,在工程实用范围内,获得了计算简捷、成果精度满足工程设计要求的简化计算公式,具有一定的实际推广意义。In order to determine the depth of the energy dissipation pool, simultaneous equations of high order are often sought after, for the conventional mathematical methods can not produce a direct solution. At present, the trial calcula- tion method, the iterative method and the approximate algorithm method are either too complicated or lack of accuracy, and the use of computer programming is not easy for the basic engineering and technical personnel. After finishing the transformation and adaption of the relative hydraulic equations, a dimensionless equation was obtained. And then the op- timal fitting method was adopted to acquire the simplified formula of this equation. According to its application in engi- neering practice, this formula is easy to use and the accuracy of its results meets the engineering requirements of accura- cy. So this formula is applicable in actual engineering practice.
