常用土方计算软件精度对比分析探讨

The discussion and comparative analysis on the accuracy of common earthwork calculation software

以榆林市榆阳区岔河则乡为研究区域,选取现阶段常用的CASS10.1、ArcGIS10.1、Surfer13、Civil 3D 2016和飞时达12.1五款土方计算软件,对土方计算结果进行对比分析。结果表明:五款软件通过三角网法计算的土方量基本相同,ArcGIS10.1和Surfer13的插值计算方法没有提高土方计算精度,原始数据的分布和密度能从根本上保证土方计算的精度;相对于基于CAD平台的软件(CASS10.1、Civil 3D 2016和飞时达12.1),基于地理信息系统的软件(ArcGIS10.1和Surfer13)数据处理速度快,可视化程度高,建模准确快速,从而使得土方计算变得更加快速准确。

Taking Chaheze township,Yuyang District,Yulin city as the study area,this paper analyzes the calculation results based on the five commonly earthwork calculation software,namely CASS10.1,ArcGIS 10.1,Surfer13,Civil 3 D 2016 and Fast TFT 12.1.the triangular network method is used to calculate earthwork.The results show that the precision of earthwork calculated by the above five software are basically the same.The interpolation calculation methods of ArcGIS 10.1 and Surfer 13 cannot improve the accuracy of earthwork calculation.The distribution and density of the original data can fundamentally guarantee the accuracy of earthwork calculation.Compared with earthwork calculation software(CASS10.1 Civil 3 D 2016 and FastTFT 12.1)based on the CAD platform,the geographic information system-based software(ArcGIS10.1 and Surfer13)has fast data processing speed,high visualization degree,accurate and fast modeling,etc.,thus making the earthwork calculation more rapid and accurate.
