基于MicroStation平台的三维地质建模探讨

Discussion on 3D geological modeling based on MicroStation platform

基于Micro Station软件开发平台,采用MDL二次开发手段,结合工程地质条件特有的复杂性,建立地形图形库、钻孔数据库、构造数据库等基础数据库,通过链接相关数据库进行空间插值分析,建立各岩层标志层的曲面,最终形成三维地质模型实体。利用数据及图形处理功能,从研究工程三维地质建模的流程及关键点出发,探讨一套适合三维地质建模的理念,展示了三维地质建模及可视化的效果。

MDL secondary development method was applied based on Micro Station software development platform,combining with the specific complexity of coal mine geological conditions, with the establishment of topography and graphics library,drilling database,structure database,etc.,through linking relative database spatial interpolation was implemented to generate hook surface of each coal rock marker bed,and finally the 3 D geological model was established.Using the data and graphics processing functions,the paper started from the research on process and key points of coal mine 3 D geological modeling,to explore a set of concept suitable for 3 D geological modeling,and demonstrated the effect of 3 D geological modeling and visualization.
