明渠设计水利技术研究现状及应用研究——以水面线计算为例

Research on the Status Quo and Application of the Water Conservancy Technology of the Open Channel Design——Taking the Calculation of Water Surface Profile as an Example

本文介绍了一种多级变截面明渠水面线的计算方法。针对传统水面线计算方法存在的精度不高、适用范围有限、工作量大等问题,应用Python语言进行编程可准确绘制出水面线图形。同时,本文深入分析了水面线计算误差产生原因,并提出了误差处理相关对策。

This paper introduces a program for calculating the surface line of multistage open channel with variable cross-section. There are a few problems with the traditional calculation method of water surface line, such as low precision, limited application range and heavy workload. Therefore, Python,a programming language, is used to accurately draw the graph of water surface line. At the same time, the paper thoroughly analyzes the causes of the calculation error of the water surface profile,and puts forward countermeasures to deal with the calculation error.
