摘　　要：FLAC3D在求解岩土工程问题方面具有许多优越性,但其在前处理(建模与网格划分)和后处理(图形结果输出)方面却存在着明显不足。对此,提出了首先利用具有强大图形与网格划分功能的ANSYS软件来实现复杂模型构建,然后通过相应程序将模型导入到FLAC3D中进行模拟计算,最后将计算结果导入到tecplot软件中进行后处理分析,用等值线来替代FLAC3D中的区域颜色,以实现结果的直观化操作流程。通过对某矿采场的建模和模拟计算,验证了该方法的优越性和可行性。FLAC^3D has many advantages in solving geotechnical engineering problems,but has obvious shortcomings in pre -processing （ such as modeling and meshing） and post - processing （such as figure output）. Therefore, this paper advances an operating process that first build complex numerical model using ANSYS software with powerful graphic and meshing functions, then import the built model into FLAC^3D using a compiled program and implement numerical simulation ,finally ,import the simulated resuits into tecplot software and implement post-processing, in which the colored zones are figured with isolines so as to made the outputted results intuitionistic. The advantage and feasibility of above method was proved by the modeling and numerical simulation on the stope of a certain mine.
