Three slope stability problems are studied with FLAC. First, a slope in sand with zero cohesion is modeled. Then, a small cohesion is added to the material and stability is reexamined. Finally, the water level in the slope is raised and the effect on stability is evaluated. The influence of a phreatic surface is analyzed in two ways: (1) an effective-stress calculation is performed after adding a pore-pressure distribution, and (2) an uncoupled groundwater-flow calculation is performed first followed by an effective-stress calculation.
