Abstract: Geological modeling has been widely applied in areas such as nonferrous metal mine exploitation,petroleum exploration,etc. Geology structure often presents non-manifold situation due to faults,resulting in relatively difficulties on complex geological structure modeling. Considering the well-behaved boundary description and the capacity adjust to constraints of Delaunay triangulation,the method of complex geological structures' modeling based on Delaunay triangulation was presented. Then the algorithm was verified by a case. The results showed that the geological structure model with geometrical consistency and grid topological consistency could be obtained by the algorithm.
