SLOPE is a computer program for analysing the stability of slopes. The program is also applicable to earth pressure and bearing capacity problems. Optional facilities are available for the analysis and design of reinforced soil.
•Analyses natural and cut slopes
•Designs reinforced earth slopes, embankments and walls
•Automatically generates slip surfaces to find the critical failure mechanism
•Surcharges and anchor loads modelled
•Multiple water tables or piezometric surfaces modelled
•Choice of circular slip surfaces or wedge analysis
•Earthquake forces modelled
•Import slope profiles from DXF or DWG files
•Graphical output of data and results
•Reinforced soil options:
 - Designs the optimum arrangement of reinforcement
 - Choice of fabric, grid or strip reinforcement or soil nails
 - Calculates reinforcement forces according to DTp procedures

The program provides a choice of methods of analysis including the following:-
•Swedish Circle (or Fellenius') method
•Bishop's method
•Spencer's method
•Janbu's method

The various methods make different assumptions about the equilibrium distribution of forces within the slipping mass. The result of each analysis is expressed as a factor of safety. In routine slope stability problems the factor of safety is calculated with respect to the strength of the soil along the slip surface. There is an option to calculate the factor of safety with respect to surcharge loads. This option is applicable to bearing capacity problems and earth pressure calculations.
