SLOPE/W 2012 slope stability analysis.
Examining force polygons for an anisotropic stability analysis

SLOPE/W is the leading slope stability CAD software product for computing the factor of safety of earth and rock slopes. SLOPE/W can effectively analyze both simple and complex problems for a variety of slip surface shapes, pore-water pressure conditions, soil properties, analysis methods and loading conditions.

Using limit equilibrium, SLOPE/W can model heterogeneous soil types, complex stratigraphic and slip surface geometry, and variable pore-water pressure conditions using a large selection of soil models. Slope stability analyses can be performed using deterministic or probabilistic input parameters. Stresses computed by a finite element stress analysis may be used in addition to the limit equilibrium computations, for the most complete slope stability analysis available.

With this comprehensive range of features, SLOPE/W can be used to analyze almost any slope stability problem you will encounter in your geotechnical, civil, and mining engineering projects.

Easy to Use

Defining a Stability Model

Beginning an analysis is as simple as defining the geometry by drawing regions and lines that identify soil layers, or by importing a DXF™ file. Then choose an analysis method, specify soil properties and pore-water pressures, define reinforcement loads, and create trial slip surfaces.

Viewing the Analysis Results

Once you have solved your stability analysis, SLOPE/W offers many tools for viewing the results. Display the minimum slip surface and factor of safety, or view each one individually. View detailed information about any slip surface, including the total sliding mass, a free body diagram and a force polygon showing the forces acting on each slice. Contour the factors of safety, or show plots of computed parameters. Then prepare the results for your report by adding labels, axes, and pictures, or export the results into other applications such as Microsoft® Excel® for further analysis.

Typical Applications

SLOPE/W can model almost any stability problem, including:

  • Natural earth and rock slopes
  • Sloping excavations
  • Earth embankments
  • Open-pit high walls
  • Anchored retaining structures
  • Berms at the toe of a slope
  • Surcharges at the top of a slope
  • Earth reinforcement, including soil nails and geofabrics
  • Seismic and earthquake loading
  • Tension cracks
  • Partial and total submergence
  • Line load at any point
  • Unsaturated soil behavior
  • plus many more!
