摘　　要：FLAC3D在地下复杂地质体实体建模及网格划分方面存在弊端。通过AutoCAD进行三维建模,将生成的AutoCAD图导入ANSYS中,可实现ANSYS的快速建模;应用ANSYS有限元程序可以快速便捷地进行网格划分,将划分后的网格文件利用ANSYS_TO_FLAC3D接口程序将其转换为FLAC3D可识别的FLAC文件。最后FLAC3D调用FLAC文件,从而实现复杂地质体的建模。详细阐述了AutoCAD、ANSYS在FLAC3D建模中的作用,并结合工程实例,验证其可行性和有效性。It has some defects in model generating of complex geologic body by using the soft ware of FLAC3D , and it also has the weak- ness in mesh generation. Aiming at this problem, firstly, AutoCAD 3D model was established, and the model file was imported into ANSYS,thus rapidly make an ANSYS model. Then it can quickly and easily realize the mesh generation by ANSYS finite element program, and then the files was converted to be the format which can be identified by using ANSYS TO FLAC3D interface program. Finally, FLAC3D calls FLAC files, established the model of complex geological body. This paper describes the role of AutoCAD, ANSYS in FLAC3D modeling and engineering examples,and verified its feasibility and effectiveness by means of engineering practice.
