该文从二维地质建模的概念出发,探讨了其一般过程,包括地质变量预测、地质特征解译、空间分析等,并介绍了三维地 质建模的体视化方法,最后以润扬长江公路大桥工程为例,运用切片级重建方法,建立地质模型,并进行了三维地质分 析。实践表明,三维地质建模技术是认识复杂地质体的空间关系和特征的强有力的工具,具有广阔的应用前景。
Based on the concept of 2D geological modeling, this paper discusses its general process, including the prediction of geological variables, the interpretation of geological features and spatial analysis, and introduces the stereo visualization method of 3D geological modeling. Finally, Highway Bridge Project as an example, using slice-level reconstruction method, the establishment of geological model, and conducted a three-dimensional geological analysis. Practice shows that 3D geological modeling technology is a powerful tool to recognize the spatial relationship and features of complex geological bodies and has broad application prospects.
