含断层地质体的三维建模方法充分利用地质剖面数据对现有线框模型进行改进,能够根据地质剖面图的特点半自动化地发现地质断层线,从而构建三维地质断层面和地层面,然后利用OpenGL加以渲染显示。本文以贵州省黔西县龙井煤矿为研究实例,在自主研发的三维地质建模软件中验证了该方法的可行性。实践表明,该方法能有效地利用现有的纸质地质剖面数据实现含断层地质体的三维建模与可视化。
The three-dimensional modeling method of fault-bearing geological body can make full use of geological profile data to improve the existing wireframe model, and can semi-automatically find the geological fault line according to the characteristics of geological profile to construct 3D geological fault plane and ground plane, and then use OpenGL Rendered to show. This paper takes Longjing Coal Mine in Qianxi County, Guizhou Province as an example, and verifies the feasibility of this method in the independently developed 3D geological modeling software. Practice shows that this method can effectively make use of the existing paper geological section data to realize the 3D modeling and visualization of fault-bearing geological body.
