SVDynamic represents a revolutionary new method of slope stability analysis that extends the capabilities of limit equilibrium methods of analysis.

Slope stability analysis is an integral part of many geotechnical engineering studies. Although numberous methods of analysis exist, the failure mechanism is still not fully understood.

Force and moment equilibrium methods can be applied to the stability problem and will provide a computed factor of safety. All limit equilibrium methods rely on a critical assumption regarding the shape of the slip surface. The normal force on the base of the slice is determined by applying statistical equilibrium to a slice from the sliding mass. The location of the critical slip surface is determined by trial and error.

SVDynamic makes use of a finite element stress analysis to compute the stress state in a soil mass. Various soil models can be used for the computation of the stress states. SVDynamic makes use of dynamic programming to calculate the most probable location of the slip surface. No assumption needs to be made regarding the shape of the slip surface since the determination of the shape is part of the solution.

The SVDynamic solution provides a global factor of safety as well as the distribution of the local factors of safety along the critical slip surface.
