基于GoCAD与Surfer平台建立三维地质模型研究

摘要

Building complex three-dimensional geological model is always a big problem to stop us going forward smoothly during the pretreatment process of FLAC 3D. Therefore, using GoCAD and Surfer as a transition, it is easy to extract and transform the information both of surface and stratums that exposed by drilling of CAD figures. Besides, complex three-dimensional geological model and mesh can be done quickly in GoCAD so that the pretreatment process of FLAC 3D is easier to be implemented. At the same time, the accuracy and simulation results are tested combined with the engineering example.%在FLAC 3D软件前处理过程中，建立复杂的三维地质体模型往往是阻挡我们顺利进行的一个大难题。因此，利用GoCAD与Surfer两个软件平台进行过渡，容易实现提取和转换CAD图中的地表以及钻孔揭露的地层信息，能够快速在GoCAD中建立出复杂的三维地质模型并成功对其划分网格，从而较简便地实现FLAC 3D复杂建模的前处理过程。同时结合工程实例，检验了此种方法的准确性和模拟效果。
