GOCAD三维地质建模成果的二次开发及应用研究

Study on application of secondary development of GOCAD 3D geological modeling results

利用GOCAD软件所建立的三维地质模型切剖面时,若要满足二维地质成果图的要求,后处理工作量相当大。利用GOCAD三维地质模型可以剖切出任意方向、任意位置剖切面的优势,二次开发出"GOCAD三维地质模型自动生成标准地质剖面图工具",可自动读取GOCAD切剖面生成文件的信息,自动搜索剖面附近钻孔地质数据,快速生成Auto CAD格式的标准地质剖面图。生成的地质剖面经技术人员修改校正,可反馈到三维地质模型中,使模型不断趋于精确。该方法成图速度快、效率高,可减轻地质人员的劳动强度。

Application of 3D geological model built by GOCAD in generation of 2D geological graph is difficult for large work- load in post processing. Taking the advantage of being capable of generating 2D profile of any direction or position by GOCAD 3D geological model, the ＂ standard automatic generation tool of geological profile by GOCAD 3D geological model＂ was developed secondarily, by which, the information of the profile generated by GOCAD can be read automatically, the geological data of sur- rounding drilling holes can be searched automatically, and the standard geological graph in AutoCAD fornmt can be produced quickly. The generated 2D graph can be feedback to 3D geological model after the modification and correction by technical staff, making 3D model more precise. This method is quick, effective, and can alleviate the work load.
