摘要
提出一种基于GIS的简单、快速和直观的3维地质建模及可视化方法。利用ArcGIS的VBA语言编写钻孔数据提取程序生成钻孔3维模型;通过空间插值工具生成地层的TIN表面模型,并基于矢量化工具获取的断裂线生成断层的3维表面模型,从而组合成地质构造的结构模型。此外,利用C#语言基于SceneControl组件开发了3维地质可视化系统原型,并对构建的地质结构模型进行了展示。系列实验结果表明,该方法具有操作简单、可视化效果好和系统开发周期短的特点,在地学研究、工程应用和其他相关领域具有一定的推广应用价值。
In this paper,a simple,rapid and intuitive GIS-based 3D geological modeling and visualization method is introduced.The borehole data extraction program was implemented based on the VBA function of ArcGIS for creating the 3D borehole models;Then,the spatial interpolation tool was used for constructing the multi-stratum TIN surface models,and the fault lines was digitized for creating the 3D faults which are combined into one geological structure model;In addition,a 3D geological visualization prototype system based on SceneControl components was implemented using C# and the constructed 3D geological was represented on it.A series test results show the methods of this paper operate not only very simply,but also can get better visualization effect,meanwhile,the short system development time is very short.As results,our methods can be widely applied for geosciences research,engineering application and other related fields.
