Stability analysis

Included within CHASM™ v4 is the Bishop method of slices. An automatic grid search specification is included which can be specified in terms of grid location, size of grid and search radius. The slip circle is then itself specified in terms of the initial radius and radius increment. The search procedure for the minimum factor of safety is then carried out by successive steps in the slip grid and changes to the radius of the slip circle. This search is carried out every hour during the simulation run time.

On completion of the simulation, a graphical output shows the grid slip surface and associated factor of safety at each hour during the total model runtime.
