摘要
应用二重积分的基本原理,研究以数字高程模型(DEM)不同分辨率确定土方量的方法。以河北省南宫市清凉江项目为例进行了计算分析,并与相关文献计算结果进行了对比,说明用该方法计算土方量是可行的。
The paper discusses how to calculate earthwork of land consolidation project using different resolutions of Digital Elevation Model (DEM) , and takes Qingliangjiang project in Nangong city of Hebei Province as a case to analyze the results and compare them to other literature. The results show that the method raised is feasible.
