RESULTS: Analysis 2
Bishop Simplified Method of Analysis - Circular Failure Surface
---------------------------------------------------------------
Critical Failure Surface Search using Multiple Circle Generation Techniques
Factor of Safety for initial failure surface approximation: 3.039
There were: 94999 successful analyses from a total of 125001 trial surfaces
30002 analyses terminated due to unacceptable geometry
Critical (minimum) Factor of Safety: 2.55
