英文摘要 | The authors present a new method for three-dimensional (3D) geological modeling from a set of topological and polygonal cross-sections, and introduce topological relationships (connectivity, adjacency and inclusion) of polygons -arcs- nodes in cross-sections to generate Triangulated Irregular Network (TIN) by connecting adjacent open arcs instead of close contours. This method is especially suitable for cases where there are several connected polygons in a cross-section, which are general in geological applications. Besides, cross-sections are not required to be planar or parallel in this method, and topological relationships are embedded in the generalized 3D geological models. Some special ideals are also proposed for some complex geological phenomena, such as stratum dying out, faults terminated within strata, etc. Finally, a 3D geological modeling and visualization software platform was developed based on this method. A case study was conducted by using the real data at the Olympic site in Beijing, China.; EI; 0; 6; 717-723; 42 |
