Abstract

The display of three dimensional geological body can visually describe the complex subsurface geological structure, effectively improve the engineer's space imagination and intuitively understand the geological spatial relationship. Through analysis of commonly used three dimensional geological data model and considered the impact of faults. The paper establishes a generalized triangular prism (GTP) element model, and achieves a three dimensional geological modeling method based on GTP. The paper proposes the error correction technology based on virtual drilling, which allows designers combine their experience to appropriately amend the unknown region of stratum, it contributes to improve the accuracy of 3D geological model. Finally, the paper achieves a 3D geological drilling, borehole cross section, visual information query and geological visualization technology such as virtual drilling, cutting, layering display based on 3D spatial analysis techniques and graphics.

Keywords: Geological, generalized triangular prism, spatial analysis, three dimensional modeling, visualization.
