A Critical Failure Surface Searching Method, Using A Random
Technique For Generating Circular Surfaces, Has Been Specified.
20 Trial Surfaces Have Been Generated.
10 Surfaces Initiate From Each Of 2 Points Equally Spaced
Along The Ground Surface Between X = 600.00 ft.
and X = 800.00 ft.
Each Surface Terminates Between X = 850.00 ft.
and X =1000.00 ft.
Unless Further Limitations Were Imposed, The Minimum Elevation
At Which A Surface Extends Is Y =130.00 ft.
10.00 ft. Line Segments Define Each Trial Failure Surface.
Following Are Displayed The Ten Most Critical Of The Trial
Failure Surfaces Examined. They Are Ordered - Most Critical
First.
* * Safety Factors Are Calculated By The Modified Bishop Method
