摘要
本文利用有限元法中网格自动生成原理和按距离加权最小二乘拟合曲面的方法,对非规则场地中给定有限个高程点时的场地土方量的计算进行了研究,给出了一种适用范围广、简便实用的土方量计算程序。
The calcalation of earthwork for irregular plane with only a few of points' height known is invesfigated and programmed by the method of mesh auto-generating and smooth surface fitting based on distance weighting.
