Application of FLAC^3D Rapid Modeling in Slope Problem of Open-pit Mine Based on Rhino3D NURBS

To make up FLAC^3D deficiency of weak pretreatment function, we introduce a method about rapid modeling of FLAC^3D based on Rhino3D NURBS. Then, taking the slope stability of dragline standing bench in Heidaigou Open-pit Mine as an example, we achieve the turning from Rhino3D model to FLAC^3D model, we test the viability and availability of the rapid modeling method.
