The perfect choice for two-dimensional slope stability analysis

Need an easy and accurate way to study a slip surface to find factors of safety against failure, and to check the improvements from reinforcement? Slope performs two-dimensional slope stability analysis using the slices methods and presents the results in a clear graphical format.

Slope is an everyday engineering tool which is quick and easy to use for a wide range of slope stability problems.  Slope is feature rich and will aid in the assessment of slopes and the design of engineering solutions for slope stability problems. A one stop engineering tool for this problem type, allowing the user to deal with soils and rock material as standard.

Powerful, flexible analysis to suit your needs

The program offers you a variety of established methods for calculating interslice forces. Choose from Fellenius or Swedish slip circle analysis, the Bishop horizontal method or the constant inclined method. For non-circular slip surfaces, the software offers you the equivalent Janbu methods. Slope also includes a variably inclined interslice force method which ensures that each slice is in equilibrium, both vertically and horizontally.

This essential slope analysis software analyses reinforcing elements such as soil nails, rock bolts, ground anchors and geotextiles to BS8007/BS8081. You can specify water pressure, material shear strength, surface loads and horizontal ground acceleration. Slope checks a range of slip circles and gives you the option to force slips through a point or keep them tangential to a strata.

Part of our Geotechnical software range, Slope is the perfect choice for anyone who needs fast and effective two-dimensional slope stability software.


  • Analysis of reinforcing elements – soil nails, rock bolts, ground anchors and geotextiles – to BS8007/BS8081
  • A variety of means of specifying water pressure including hydrostatic below a phreatic surface, piezometric or Ru values
  • A variety of methods of specifying material shear strength including drained or undrained parameters which may vary with depth
