RESULTS: Analysis 1 - Westgate Road, Seismic
Bishop Simplified Method of Analysis - Circular Failure Surface
Critical Failure Surface Search using Multiple Circle Generation Techniques
Initial failure surface approximation - Factor of Safety: 1.249
Analysis Summary
There were: 1812 successful analyses from a total of 2001 trial failure surfaces
189 analyses terminated due to unacceptable geometry
Critical (minimum) Factor of Safety: 1.18
Negative normal stresses exist on the base of one or more slices; examine slice data
and consult the GALENA Help utility
