摘要
对土方量均衡计算与场地平整进行分析研究,利用AutoCAD下土方量计算的特点,以AutoVBA为二次开发语言,进行格网(Grid)和三角网(TIN)两种DEM模型的建立,在两种模型下通过给定设计标高求出平整区面积和需要的填、挖方量,实现了一定区域的土方量计算。最后对两种模型下计算结果进行比较,总结了三角网独特的优点。
By analyzing and research the field leveling and equilibrium calculation, according to the features of equilibrium calculation under AutoCAD, taking Auto VBA as the second developing language, this paper constructs the Grid and TIN DEM models, and realizes the equilibrium calculation in certain region and the results comparison of two models, then establishes the foundation for, field leveling. It summarizes the particular advantage since comparing the two results.
