FLAC/SlopeVersion 8.1 -Graphical Interface Software

SHARE

FLAC/Slope is a special, streamlined version of FLAC for evaluating the factor of safety (FoS) of soil and rock slopes in two dimensions with simple and fast model setup and analysis execution. FLAC/Slope can simulate stability problems under a wide variety of slope conditions, including: arbitrary slope geometries, multiple layers, pore pressure conditions, heterogeneous soil properties, surface loading, and structural reinforcement.
