摘　　要：三维地质建模在探测矿产资源中具有重要作用,金属矿瘤等多值地质界面模拟是三维地质建模难点。本文提出在三角网格拓扑结构基础上,引入固定控制点和模糊控制点作约束条件,结合三角形网格细分方法,利用动态DSI插值法控制网格面的生成,实现多值地质界面模拟方法 ;并以蘑菇形矿瘤多值地质界面为模型实例,实例表明以该算法具有良好实用性。Three-dimensional geological modeling plays an important role in the exploration of mineral resources.Multivalue geological interface simulation such as metal ore tumor is a difficulty in three-dimensional geological modeling.In this paper,based on the triangular grid topological structure,fixed control points and fuzzy control points are introduced as constraint conditions,and the generation of grid surface is controlled by dynamic DSI interpolation method combined with the triangular mesh subdivision method to realize the multi-value geological interface simulation method.Taking the multivalue geological interface of mushroom rock as an example,the example shows that the algorithm has good practicability
