摘要
本文根据梯形渠道明渠均匀流计算理论,分析了求解渠道正常水深的迭代法的基本原理及方法,给出了梯形渠道正常水深迭代法求解直接计算公式。此迭代法求解公式不仅收敛快,计算精度高,应用方便,而且可供计算机程序求解。
Based on the calculation theory for even -flow in trapezoid open channel, the author analyzed the basic principle and procedures of iteration method to solve the normal water depth value of channel and proposed a direct calculation formula of normal water depth in trapezoid open channel for optimal hydraulic section. This iteration calculation formula possessed properties including fast convergence, high accuracy and convenience for use, and can be operated through computer program.
