RANK-D.OPT
Unless further limitations were imposed, the minimum elevation
at which a surface extends is y = 50.0 ft
* * * * * DEFAULT SEGMENT LENGTH SELECTED BY XSTABL * *
4.0 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 :_ -95.0 degrees
Upper angular limit :_ -1.0 degrees
Factors of safety have been calculated by the
* * * * * SIMPLIFIED BISHOP METHOD
The most critical circular failure surface
is specified by 20 coordinate points
