摘要
由于潜坝的水力计算涉及超越方程求解问题,具体解算过程需反复试算,又因其流量系数是通过曲线图给出,每次试算必须借助曲线图查取数值,不但过程繁复,而且查图取值的人为误差又不可避免。为了简化潜坝的水力计算过程,提高求解成果精度,采用优化拟合的方法,完成了流量系数曲线图的函数拟合,提出了水力计算的迭代公式,有效简化了求解过程,提高了成果精度。
Because the hydraulic calculation of submerged dam involves the solving of transcendental equations,it needs to make trial calculations repeatedly.And because its flow coefficient is given by diagram and the checking for values must be helped also by diagram,not only the solving process is complicated,but also the human errors in the checking for values are inevitable.In order to simplify the hydraulic calculation of submerged dam to improve the accuracy of the solving results,the optimal fitting method is used here to complete the function fitting of flow coefficient diagram,and propose the iterative formula of the hydraulic calculation,which would simplify the solution process effectively and improve the accuracy of results.
