摘要
断面法计算冲淤量在水库或河道冲淤分析、演变分析等工程中具有广泛的应用,具有原理简单、运算方法简洁,便于实现等优点。但是计算结果受断面位置的代表性、测量数据精度和断面间距影响较大。本文分析了断面法计算冲淤量的主要方法和影响因素,采用VB编程语言实现断面法计算冲淤量,输出需要的长度、槽蓄量、面积、冲淤量、冲淤厚度等结果,具有一定的工程应用价值。通过工程应用实例计算与ArcGIS冲淤分析对比,来验证程序的可靠性。
The section method is widely used in the analysis of erosion and deposition of reservoirs or rivers,evolution analysis and other projects.It has the advantages of simple principle,simple calculation method and easy implementation.However,the calculation results are greatly affected by the representativeness of section position,the accuracy of measurement data and the distance between sections.This paper analyzes the main methods and influencing factors of calculation of scouring and silting by cross-section method.VB programming language is used to realize the calculation of scouring and silting amount by cross-section method,and outputs the required length,channel storage,area,scouring and silting amount,scouring and silting thickness,etc.,which has certain engineering application value.The correctness of the program is verified by comparing the calculation of engineering application examples with the analysis of erosion and deposition in ArcGIS.
