中文摘要：
直接利用FLAC^3D软件建立复杂三维地质模型比较困难。而使用AutoCAD软件可以建立复杂三维模型，且方便、快捷和精确．将AutoCAD软件建立的复杂三维模型导入到ANSYS软件中，使用ANSYS软件对模型进行网格划分，使用ANSYS软件与FLAC^3D软件的接口程序。将ANSYS软件已经划分过网格的三维模型的单元数据转换为FLAC^3D单元的数据，在FLAC3D软件中导入三维模型，从而实现在FLAC^3D软件中快速建立复杂三维地质模型．这为利用FLAC^3D软件对复杂三维地质模型进行分析提供了一种便利的手段．该方法借助于AutoCAD软件的优点，使得在FLAC^3D中精确快速建立复杂地质体三维模型更快捷用此法建立贵州瓮福磷矿的某一复杂三维边坡FLAC^3D模型，对该模型进行了稳定性分析．经分析该边坡的安全系数为3．03，边坡处于稳定状态．借助于该法可使利用FLAC^3D进行复杂三维模型的分析更快捷．
英文摘要：
It is difficulty to create three dimensional numerical model in FLAC^3D. But it is very easy to do this with AutoCAD software, and it is convenient and accurate. The model created by AUTOCAD is exported to ANSYS, then it is meshed. The information of the element can be translated into the format which earl be recognized by FLAC3D with the interfaee between ANSYS and FLAC3D. The model earl be import into FLAC3D.Then this is a fast method to create three dimensional numerical model in FLAC3D. One model of one slope of the WENGFU phoshate is created by this method. The stability of the slope is analyzed with this model. The slope is steady. The safety factor is 3.03 with this situation. The efficiency of numerical simulation can be greatly enhanced with FLAC3D software in simulating complex three dimensional model.
