and x = 234.5 ft
Each surface terminates between x = 330.0 ft
and x = 400.0 ft
Unless further limitations were imposed, the minimum elevation
at which a surface extends is y = 90.0 ft
* * * * * DEFAULT SEGMENT LENGTH SELECTED BY XSTABL * * * * *
9.0 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 -1.0 degrees
Factors of safety have been calculated by the

The most critical circular failure surface
is specified by 17 coordinate points
