| Abstract: | Propose a new method for 3D computerized modeling of geological objects from sets of intersected folded cross-sections, and especially solve the two key problems of "high-precision modeling" and "rapid modeling". This method expands source data and improves automatization degree for 3DGM. Besides, reconstructed geological objects are more real and smoother, and model quality is improved. Finally, a 3D prototype system has been developed based on this method. A case study at the Olympic site in Beijing, China shows that the method can be applied to practical geological areas. |
