摘要
针对FLAC3D面向复杂的地质模型建模存在的技术困难和不足,提出CATIA-FLAC3D耦合建模新方法。先利用CATIA强大的三维地质体建模功能进行三维地质建模,再利用其有限元模块对地质体进行网格划分;基于对两类软件中单元、节点数据关系的差异分析,应用Visual Basic语言编写CATIA-FLAC3D接口程序,实现了将CATIA环境下建模生成的单元、节点信息导入FLAC3D。以某已建成偏压隧道工程为例,验证了CATIA-FLAC3D耦合建模方法的可行性和有效性,为FLAC3D构建三维复杂工程模型提供了新的思路。
Numerical models based on FLAC3D are difficult to build. A new kind of method modeling and meshing in the CATIA software, named the CATIA-FLAC3D coupled modeling method, was proposed. This method utilizes the powerful geological modeling capabilities of CATIA for three-dimensional geological body modeling and meshing. And then, the interface program of CATIA-FLACsD is adopted to export the information into FLAC3D, which is coded by visual basic language based on the variance of nodes and elements between the two software. The new proposed method was used in a bias tunnel through a mountain, and the results verified the feasibility and effectiveness of the proposed method.
