Slope /w For Slope Stability 
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 or QUAKE 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 to the conventional factor of safety.
