| 摘 要： | 人工渠道中的水流绝大多数是非均匀流,分析计算其水面曲线的变化规律是确定明渠边墙高度及回水淹没范围的重要依据,因此在工程实践中具有十分重要的意义。传统方法推求水面线一般采用试算法或图解法,其法计算速度慢、精度低。本文通过开发软件,实现人机对话,利用C语言编制计算机程序,结合内插法,可快速准确的推求出水面曲线。 |
| 关 键 词： | 非均匀流 水面曲线 计算机 |

| Abstract: | Most of wter flow in open-channel or in river belongs to steady non-uniform flow.The surface profiles are caused by changes of channel section.It is very important to analyze its computations.According to the regularity of its surface change,the suitable sectional dimensions of open channel or flood control work can be designed.Commonly,computation of non-uniform flow adopts the traditional methods by hand or by graphic method.The speed and precision of computation are restricted.In this paper,a software to calculate water surface curve is introduced.The software is put forward by using C .By means of interpolate method and dialogue between user and computer,we can calculate the water surface curve much more quickly and exactly. |
| Keywords: | non-uniform flow water surface curve computer |
