利用ArcGIS进行土地平整土方量计算的应用

Application of the Earthwork Calculation at Land Development Based on ArcGIS

挖填土方量的计算是土地整治项目的重要组成部分。在已有计算方法的基础上,结合多年从事土地整治项目的实际经验,探讨Arc GIS在土方量计算中的应用,并以某一工程实例对研究区的土方填挖量进行计算。结果表明,利用Arc GIS进行土方量计算具有操作简单、精度高、速度快的优点,能够实现三维可视化,具有可行性。

The earthwork excavation is an important part of land development project.Based on the existing calculation methods and combined with years of practical experience in land development projects,we explored the application of ArcGIS in the calculation of earthwork.A certain engineering example was taken as the researching area to calculate the amount of earthwork excavation.The results showed that applying ArcGIS to calculate earthwork had the advantages of simple principle,fast speed and good feasibility,so that the three-demon-signal visualization could be realized and this method was feasible.
