Method of Rapid Modeling in FLAC^(3D) Fault Simulation Based on AutoCAD

针对采用接触面法和弱化法进行FLAC^(3D)断层建模时断层两侧模型网格节点对接困难、节点密度不易控制的问题,利用岩层分层建模的方法,并采用java语言编制中间程序,研究了一种将基于AutoCAD的二维平面图形便捷高效地转换为FLAC^(3D)网格模型的方法。该方法基本实现了建模过程的可视化和自动化,提高了建模效率,解决了复杂地质条件下的快速建模问题。

In this paper, according to the problems of hard connection and management of the density of mesh nodes on both sides of FLAC^（3D）fault modeling by using interface method and weakening method, with the method of layered stratum modeling and intermediate program writing by using Java language, an approach to convert two-dimensional planar graph based on AutoCAD into FLAC^（3D）mesh model conveniently and efficiently was studied. The approach has basically achieved the visualization and automation of modeling process, improved the modeling efficiency and solved the problem of rapid modeling under complicated geological conditions.
