基于ArcGIS的填挖方量算法研究与实现

Research and realization of cut/fill computation method based on ArcGIS

从实际工作的需求出发,结合目前相关算法的缺憾,提出了一种既能保证计算精度又可以满足实际需求的填挖方量算法。在对该算法流程进行详细分析后,提出了基于ArcGIS的该算法实现方法。以某跨海大桥施工疏浚工程项目为实例,建立了一个填挖方量计算模块,并进行了相关的精度分析。

Based on the actual need and the shortage of the correlative computation, the computation method which can ensure the precis＇on and meet the actual need of cut/fill computation is introduced in the paper. After analyzing the process of the computation, the author gives the method to implement the computation based on AreGIS, and then establishes an application module of cut/fill calculation for a sea- span bridge. After giving the analysis on the precision of the computation, the author affirms the compution further .
