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.
