摘要
研究目的:为了实现土地整理中土方量计算的准确、快速、方便和自动化。研究方法:应用数字高程模型(DEM)原理,结合土方量计算的方格网法,借助ERDAS IM AGINE遥感图像处理软件,建立土方量计算模型。研究结果:以江西省九江县港口街镇土地整理项目为例介绍了计算的详细步骤,计算结果比专家论证批复的项目设计土方量大4.4%。研究结论:该方法计算土方量是可行的,能够实现土方量的计算机辅助计算。
The purpose of this study is to realize the automatic, simplified and precise earthwork calculation in land consolidation project. Methods of DEM and grid principle were employed. A model was built using ERDAS IMAGINE software. Gangkoujie Project in Jiujiang of Jiangxi Province was taken as a case to introduce detailed process of earthwork calculation, and the result is only 4. 4% more than the earthwork calculated by experts. It is concluded that this model is feasible and reliable, and has capability to realize compute - aided earthwork calculation.
