Unless further limitations were imposed, the minimum elevation
at which a surface extends is y = .0 ft
* * * * * DEFAULT SEGMENT LENGTH SELECTED BY XSTABL *
6.0 ft line segments define each trial failure surface.
ANGULAR RESTRICTIONS :
The first segment of each failure surface will be inclined
within the angular range defined by :
Lower angular limit :_ -45.0 degrees
Upper angular limit :_ -5.0 degrees
Factors of safety have been calculated by the :
SIMPLIFIED JANBU METHOD
