摘　　要：针对FLAC3D数值模拟软件在复杂三维建模以及网格划分等前处理中存在的不直观、工作量大等问题,提出了基于Auto CAD与HYPERMESH软件自动生成复杂地质体FLAC3D模型的方法。该方法以地质地形图及岩层柱状图为原始资料,通过Auto CAD、HYPERMESH软件进行三维实体建模并划分网格,再利用编写的接口程序转换生成FLAC3D计算模型,实现了FLAC3D计算求解。最后,以陕北黄土沟壑区地形为实例,验证了该方法快速精准建模的实用性和有效性。Against shortcomings of FLAC3 Dnumerical simulation pretreatment in complex 3D Modeling and element mesh dividing,an automatic FLAC3 Dmodel generation method for complex geologic body, which used HYPERMESH and FLAC^3D for 3D Modeling and element mesh dividing,according to the geological topographic map and the stratigraphic column,an interface program to transform and create the FLAC3 Dcalculation model. And the validity and practicable practicability was verified,taking loess hill and gully area of northern Shaanxi province was taken as a sample.
