RESULTS: Analysis 2 - Lab Scenario 3 pt2
Bishop Simplified Method of Analysis -Circular Failure Surface
--------------------------------------------------------------
Critical Failure Circle Search using Multiple Circle Generation Techniques
Factor of Safety for initial failure circle approximation: 3.91
There were: 53416 successful analyses from a total of 125001 trial circles
71585 analyses terminated due to unacceptable geometry
Critical (minimum) Factor of Safety: 3.85
Negative normal stresses exist on the base of one or more slices - examine slice data and consult the GALENA Help utility
Test Factor is less than 0.2 lower limit for one or more slices - examine slice data and consult the GALENA Help utility
