Abstract
The aim of our work is to investigate the comparative performance of three different software packages. Slope stability of an open pit phosphate mine was studied using numerical methods, finite element (FEM) and finite difference methods (FDM). More specifically, the widely used geotechnical software FLAC 2D of Itasca Consulting Group Inc., PLAXIS 2D of Plaxis bv and Phase2 of Rocscience Inc. are used by applying the so-called shear strength reduction (SSR) technique under Mohr-Coulomb constitutive models. The scope of the work is to compare the solutions obtained for the exact same problem from the three software packages and to discuss the comparative similarities and differences among them.
