河道水面线编程计算方法及工程应用研究

摘要

In order to solve the problem of big calculation and poor accuracy when the traditional method was applied to calculate the water surface profile of a longer river with more sections,the paper used C+ + programming to calculate the channel surface line according to the basic principle of water surface profile calculation and the relationship between the water lever and hydraulic factors by CAD and Excel analysis. The results of ex-ample show that the new method is efficient and feasible and can meet the need of engineering calculation.%为了解决传统水面线计算方法在较长河道多个流段水面线计算中存在的计算量大且精度不高等问题，从水面线推求的基本原理出发，用CAD和Excel软件分析了水位与水力要素的关系，然后通过C＋＋软件编写程序进行河道水面线推求。实例分析结果表明，该方法计算过程简单快速且结果的精度较高，能满足工程计算的需要。
