To help interpret the results, various parameters can be plotted along the critical slip surface, including:

- Frictional and cohesive strength
- Shear resistance
- Base normal
- Interslice normal and shear forces
- Seismic force per slice width
- Pore-water pressure
- Local stability factor when using the Finite-Element Stress Method

- Natural earth and rock slopes
- Sloping excavations
- Earth embankments
- Open-pit high walls
- Anchored retaining structures

SLOPE/W can also calculate a stability factor based on SIGMA/W finite-element computed stresses. Once a stress analysis has been completed, SLOPE/W can compute both the total shear resistance and mobilized shear stress along the entire slip surface in order to assess the margin of safety in terms of a stability factor. In addition, SLOPE/W computes a local stability factor for each slice. To use this optional feature, you must have SIGMA/W as well as SLOPE/W.

- Probabilistic Slope Stability Analysis
- Increased Performance
- Improved User Interface -Toolbars, status bar, The File menu lists the previous six SLOPE/W problems that you have opened, new Windows 95 common dialog boxes are supported.
- Online Help and User's Guide
- Enhanced Soil Models - Most soil models have been enhanced to handle anisotropy. You can now define a function to make the soil strength dependent on the slice base inclination. In the Anisotropic Strength soil model, both c and can be assigned anisotropic strength modifier functions. SLOPE/W now has an additional soil model that allows you to specify the strength as a function of the effective overburden stress.
