Comprehensive and Powerful 
SLOPE/W is the leading software product for computing the factor of safety of earth and rock slopes. With SLOPE/W, you can analyze both simple and complex problems for a variety of slip surface shapes, porewater 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 porewater pressure conditions using a large selection of soil models. 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.

Formulation 
SLOPE/W is formulated in terms of moment and force equilibrium factor of safety equations. For example, the MorgensternPrice method satisfies both force and moment equilibrium.
This general formulation makes it easy to compute the factor of safety for a variety of methods and to readily understand the relationships and differences among all the methods.
SLOPE/W can use finite element computed stresses from SIGMA/W or QUAKE/W to calculate a stability factor by computing both total shear resistance and mobilized shear stress along the entire slip surface.
SLOPE/W then computes a local stability factor for each slice.
Probabilistic analysis can be performed by using normal distribution functions to vary soil properties and loading conditions. Using a Monte Carlo approach, SLOPE/W computes the probability of failure in addition
