基于钻孔数据三维地质体的数据结构的描述

Describing 3D Geological Body With Data Structure Based On Borehole Data

针对数字矿区和岩土工程中基于钻孔数据和剖面数据建模问题,提出了一种适合描述基于钻孔数据三维地质体的数据结构。并在Visual C++6.0编程环境下,借助于OpenGL图形库,实现了复杂地质体建模及可视化。通过实验数据验证,该数据结构不但在很大程度上提高了建模效率和实现数据的动态更新,而且提供了三维的空间交互、查询和分析功能。为我国矿山三维地质建模及可视化软件中数据结构的设计提供了参考,促进了我国矿山信息化的建设。

According to the problem of modeling based on Borehole l and section data,a new kind of data-structure is presented to describe 3D geological body structure based on bore hole data.Based on OpenGL library,the 3D geological modeling and visualization of complex geologic body is achieved in Visual C ＋＋ 6.0.Lab data test shows that the data-structure not only can improve modeling efficiency and update data automatically but also can prove the functions of three-dimensional spatial intersection,query and analysis.It provides reference for design of 3D geological modeling and visualization software,and promotes the informatization construction in mine.
