摘　　要：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。This paper proposes an effective method for building 3Dmodels of geological faults based on section map data.To semi-automatically discover geological fault lines,existing wire-frame model is used and improved through taking full advantage of the characteristics of geological section data.A series of process flows are put forward to process section data and generate 3D models of fault plane and strata.Then,the 3D geological models can be rendered and displayed by OpenGL.Furthermore,the proposed method is implemented in a self-developed 3Dgeological modeling software.A concrete example of using the method to geological faults in Longjing coalmine,Guizhou Province shows that the method can carry out 3D modeling and visualization of geological bodies including faults by utilizing section map.
