FLAC/Slope

FLAC/Slope uses the graphical interface and the automatic factor-of-safety calculation of FLAC as the core of a user-friendly code that models slope stability problems under a wide variety of slope conditions. These include: arbitrary slope geometries, multiple layers, pore pressure conditions, heterogeneous soil properties, surface loading, and structural reinforcement.


Highlighted Features

  • Specialize version of FLAC with a streamlined user interface for evaluating the factor of safety (FoS) of slopes;
  • Uses Shear-Strength Reduction (SSR) method to calculate FoS;
  • Simple, fast model set-up and analyses execution;
  • Wizards for slope, bench, dam, and general topography;
  • Include 3D structural ground support (rock bolts, soil nails, and geogrids);
  • Include an interface between materials to model geological or artificial surfaces;
  • Axisymmetric or plane strain analyses;
  • Specify the location of a water table for effective stress analysis;
  • Apply forces;
  • Specify the materials either manually or from a database;
  • Specify geological layers; and
  • Plot calculated FoS, velocity vectors, shear strain, and plasticity indicators.
