Contrastive Analysis between Flac & Flac3D in Steep End-Slope Mining Design

The steep end-slope mining design is sensitive to stability factor of the slope.The given slope profile is often analyzed with Flac,and Flac3D with an expanded slope model.In the paper,a series of slopes with different height were analyzed with Flac and Flac3D.The result shows that it is superior using Flac than Flac3Din open-pit slope stability factor analysis when there is only slope profile available.
