摘要
采用基于AutoCAD平台的Object ARX二次开发技术,以测量数据和钻孔数据为基础,编程建立各地层界面模型,通过面域拉伸和实体布尔运算等方法生成工程地质三维实体模型。其中,地表模型的建立直接采用测量数据,形成Delaunay三角网面域;地表以下各地层模型的建立则是利用Surfer对地层钻孔数据进行插值拟合,形成三维网格数据文件,导出为"*.dat"文件后,利用Object ARX二次开发技术编程建立地层三角网面域。研究结果表明,用该方法建立的模型,不仅能真实反映工程所处的地质环境,而且极大地提高了设计工作效率。
Based on the measured data and drilling data,interface models of various engineering geological strata are built by using Object ARX derived from the Auto CAD platform. Then,the 3 D geological entity model is generated by the method of region stretching and solid Boolean operation. Among them,the surface model is built directly using the measured data,which forms the Delaunay triangulation area. Other stratum models below the surface are built by Surfer to interpolate and fit the borehole data,which forms the 3 D mesh data files. Then the data is exported as the ＂ ＊. dat＂ file,and further forms the stratigraphic triangulation area by Object ARX. The results show that the model established by this method can not only reflects the geological environment of the project,but also greatly improves design efficiency.
