基于GOCAD的复杂地质体FLAC^3D模型生成技术

摘要

鉴于FLAC3D难以建立复杂三维地质体的缺陷和GOCAD强大的地质建模能力,本文提出了基于GOCAD软件建模和划分网格,并通过GOCAD与FLAC3D的接口程序,将其导入FLAC3D的复杂三维地质体建模方法,从而实现了复杂地质体FLAC3D模型的直观、快速建模。该建模方法在郴宁高速公路某软土地基斜坡高填路堤建模中得到了实际应用,结果表明该方法是完全可行和有效的。%Aiming at the disadvantages of FLAC3D modelling,and according to the powerful geological modelling capabilities of GOCAD,a new kind of method to establish a three-dimensional complex geological body model is proposed in this paper.The method is modelling and meshing in GOCAD software,and import this model to FLAC3D by the interface program between GOCAD and FLAC3D,to construct the FLAC3D model automatically and fleetingly.The new modeling method has been used in building a high filled embankment model,which embankment is on slope soft-soil foundation of Chen-Ning highway in Hunan province,and the result shows that the new modeling method is feasible and effective.
