摘要
对数字高程模型分析中常用的内插方法进行了介绍,对拉格朗日(Lagrange)内插法、不规则三角网(TIN)内插、标准格网内插法进行了算法研究并在工程应用中编写计算机程序,在深圳软地基处理的沉降监测工程中对监测样本点的沉降进行内插计算和分析。
This paper introduced the Finite Element Method for digital elevation model analysis.Then it discussed the algorithm of Lagrange＇s interpolation method,Triangulated Irregular Networks（TIN） interpolation method,and standard grid interpolation method.It realized the computer program in the application of engineering,and carried out the interpolation calculation and analysis for the settlement of monitoring sample points for soft subgrade treatment in Shenzhen.
