复杂地质体三维数值建模方法研究

针对建立复杂三维地质体模型难度较大的问题,提出了一种有效的建模方法。该方法是以钻孔柱状图为原始资料,首先利用SURAPC软件生成岩层等高线,然后使用CAD和ARCGIS软件生成了网格点坐标,接着在ANSYS中建立实体建模并划分网格,从而建立有限元模型,再利用接口程序在FLAC3D中生成计算模型。最后,以甘肃窑街煤电集团天祝煤矿三维建模为实例,验证了该方法的可行性和有效性。

3D modeling method of complicated geological body

Because of the difficulty of the complicated geological body modeling, an effective modeling method was put forward. The method is based on the drilling synthetic plot for the original data, it uses SURPAC software to generate the rock contour at first, and then uses CAD and ARCGIS software to generate the coordinates of the grid points, then builds up the solid model by ANSYS and establishes the finite element model through meshing. The computational model was generated by the use of interface program at last. In the end, the 3 D numerical model of TIAN ZHU coal mine of YAO JIE Coal Electricity Group Limited Company of GAN SU was developed and the case study shows the utility and efficiency of the method.
