| 摘 要： | 对三维模拟插值问题进行了探讨,指出现有的一些插值算法不适应信息点较少的情况.介绍了B-样条插值的有关理论和特点,在此基础上,构造了一种基于稀疏点信息的三维模拟插值算法.该算法的思想是将三维插值问题化作稀疏矩阵的插值问题,利用B-样条函数分别对稀疏矩阵的行和列进行插值操作,形成满阵.在实际工程中,利用该算法对某采空区进行三维模拟计算,采用一类边界条件,取得了较好效果.

| Abstract: | This paper discusses an interpolation algorithm of 3-D simulation based on sparse points,points out the problem of less not-adaptive points in some interpolation algorithms,and introduces the theory and characteristics of Basic Spline Interpolation.Consequently,this paper designs a 3-D interpolating algorithm based on sparse point information,which changes 3-D interpolation problems into interpolation problems of a sparse matrix,and uses the basic spline function to interpolate values in rows and columns respectively to form full matrix.Thereafter,this paper conducts 3-D simulation in a mining area with the first boundary conditions with good effectiveness. |
