摘要
为了对地质构造形态、特征有简明直观的认识,帮助决策人员做出更为合理的判断,在深入研究三维地质建模的基础上,采用基于离散网格曲率动态地在三角网中选取合适的插值点,使用克里金算法计算待插值点的高程值,生成的三角网中三角形个数较少,同时准确地描述地层面的结构特征,解决了建模方案不清晰、数据冗余和计算缓慢等问题,极大优化了三维地质建模的效率。
In order to help decision-makers to make more reasonable judgments on the geological structure and the characteristics.A new method is proposed in this article based on in-depth study of 3 D geological modeling.It adopts appropriate interpolation point which is based on discrete grid curvature and applies Kriging algorithm to calculate the elevation value of the points to be interpolated.This method generares less triangles accurately,describes the structural characteristics of the ground level and solves the problems such as unclear modeling program solution,data redundancy and slow calculation which optimizes the efficiency of three-dimensional geological modeling significantly.
