基于DEM的渠道土方量计算模型

Calculating Model for Earth Volume of Canal Based on DEM

针对传统断面法土方量计算效率低的问题,提出一种基于数字高程模型(DEM)的渠道土方量计算模型,并在目前应用最广泛的计算机辅助设计软件——AutoCAD下利用ObjectARX技术编程实现该模型。

Calculating earth volume by regular method is not only onerous but also low precision.so,the calculating model for earth volume of canal based on DEM was advanced in this issue,then,this model was realiaed on AutoCAD by ObjectARX programming.
