摘　　要：针对ArcGIS软件复杂钻孔三维精细地质模型自动构建研究存在的不足,该文在简要分析MultiPatch三维空间数据模型和深入研究复杂钻孔三维空间精确定位方法的基础上,探讨了基于ArcGIS Engine的复杂钻孔三维精细地质模型自动构建工作流程,并从空间精确定位、属性精细表达两个层面对钻孔三维精细地质模型构建算法进行了设计与实现。经软件功能研发及实际应用检验表明,该研究能够有效实现复杂钻孔精细地质属性特征的三维空间精确定位及多尺度精细表达,为应用ArcGIS Engine自动构建复杂钻孔三维精细地质模型提供了一种新的有效途径,也可为基于ArcGIS Engine的复杂地质体三维可视化建模及精细地质属性表达研究提供应用借鉴。Accurate coordinates and detailed geological features of geological bodies can be obtained through boreholes data in 3D space, which are important data sources for 3D detailed geological modeling. Aiming at the lack of 3D boreholes detailed geolog- ical auto-modeling in ArcGIS software, based on a brief analysis of MultiPatch 3D spatial data models and a further study of 3D spatial precise positioning for complex boreholes, the workflow of 3D boreholes detailed geological auto-modeling were discussed by extending MultiPatch 3D spatial data models, and those algorithms of the accurate positioning and the spatial attribute de- tailed expression for 3D boreholes detailed geological auto-modeling were designed and implemented. Through the software de- velopment and the actual mines＇ applications,the results show that the research could realize multi-scale automatic expressions of 3D boreholes spatial information and detailed attributes, which can provide an effective way for 3D boreholes detailed geolog- ical auto-modeling based on ArcGIS Engine. Those algorithms discussed in this study are practical and effective, which also can provide an application reference for 3D visualization modeling in complex geological bodies based on ArcGIS Engine.
