摘要
挖深式消力池深度的计算在以往均采用隐式试算法,计算难度大。因此提出一种显式试算法,可以简化消力池的计算过程。根据挖深式消力池深度计算的4个基本方程,利用范盛金公式求解一元三次方程的方法和数值分析方法,对挖深式消力池深度计算的显式试算法进行了研究。给出了消力池跃前断面水深的显式计算公式和消力池深度的显式试算公式,通过实例说明了显式试算法的计算步骤。显式试算法与传统隐式试算法比较,精度与传统试算法一致,但计算过程相对简单的多。
The calculation of the depth of the excavation depth in the past are used in the implicit trial method, the calculation is difficult. Therefore, an explicit trial algorithm is proposed to simplify the calculation process of stilling pool According to the four basic equations of depth calculation of deep excavation depth, the method and numerical analysis method of solving one yuan cubic equation by using Fan Shengjin＇s formula are studied. The explicit trial method of depth calculation of deep excavation is studied. The explicit calculation formula and the explicit formula of the depth of the stilling basin are given, and the calculation steps of the explicit trial method are illustrated by an example. Explicit trial method and traditional implicit trial method, the accuracy of the same with the traditional test algorithm, but the calculation process is relatively simple and more.
