面积插值法在梅桥水库库容测量中的应用

Application of Area Interpolation in Calculating the Capacity of Meiqiao Reservoir

摘要: 目前测量中常用的断面法体积计算公式是不严密的,文中引入了严密体积计算公式并进行了证明,后又首次引进了拉格朗日四点面积插值公式,可对地形变化情况复杂区断面间的面积进行插值计算,再根据这些插值就可计算出准确的体积量。

Abstract: The normal formula of cross-section volume calculation is not accurate.An accurate formula is applied and proved in this article.It is first to use the Lagrange formula of four points area inserting value.This formula can deal with the area calculation of complex terrain,and the accurate volume can be got according to the area inserting value.
