Geological feature-driven three-dimensional geological modeling technology

3D geological Modeling are divided into two categories: geometric model & attribute model, The geological survey data collected are also divided into geometric data and attribute data. In this paper, a geometric model is constructed based on spatial data. By solving the geometric mapping and topological correlation based on geological features, the topological relationship between attribute data of various geological features and graphic elements of geometric model is established, and the effective constraints of attribute data and geometric data are realized. Finally, a three-dimensional geological model driven by geological features satisfying the unique topological relationship is constructed. This technology solves the effective fusion of geometric data and attribute data, provides a comprehensive three-dimensional model for geological comprehensive analysis and engineering application, and validates it with actual engineering data, and achieves good results.
