基于Kriging插值DEM的计算土方量方法的研究
Method of calculating earthwork based on the DEM of Kriging interpolation
【摘要】 基于DEM的土方量计算是当前的主要方法,DEM精度基本决定土方量的计算精度,提高DEM精度是提高土方量的计算精度的根本。基于Kriging插值法能获得高精度DEM。本文通过对一个大型矿山的堆料体积的测量,并对Kriging方法及其它三种方法计算出的土方量(堆料体积)进行比较,证明了Kriging法是一种高精度土方量计算方法。
【Abstract】 Calculating earthwork based on the DEM currently is a main method.The precision of earthwork calculation depends on that of the DEM,so it is important to improve the precise of DEM.The DEM based on Kriging interpolation has a good precision.In this paper,the authors measured volume of stack of a large-scale mine with four different methods.The result showed that earthwork calculation based on the DEM of Kriging interpolation was high-precision,but others were not.
