针对三维地质建模中数据繁多、建模参数选取及地层建立过程复杂等问题,采用C#程序语言结合Auto CAD和CATIA进行二次开发,提取并归类数据,同时借助CATIA强大的建模功能,建立地形实体,根据多曲面随机组合分割原理,完成对地形实体的分割,实现了三维地质建模的自动化,并将其应用于实际工程中。结果表明,在数据提取中采用图层堆叠的方式对于海量数据处理具有一定优势,经优化后的三维地质建模思路能较好地实现程序化,简化建模过程。研究成果为三维地质建模提供了参考。
Aiming at the problems of many data in 3D geological modeling, the selection of modeling parameters and the complicated process of formation formation, C # programming language is used for secondary development of Auto CAD and CATIA to extract and classify data. At the same time, with CATIA’s powerful modeling capabilities, The terrain entity is established. According to the principle of multi-surface random combination segmentation, the segmentation of the terrain entity is completed. The automation of 3D geological modeling is realized and applied to practical engineering. The results show that the method of layer stacking in data extraction has certain advantages for mass data processing. The optimized three-dimensional geological modeling can better program and simplify the modeling process. The research results provide a reference for 3D geological modeling.
