NORTH.OPT
10 Surfaces initiate from each of 100 points equally spaced
along the ground surface between x = 95.0 ft
and x = 105.0 ft
Each surface terminates between x = 236.0 ft
and x = 250.0 ft
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 -45.0 degrees
upper angular limit -1.0 degrees
Factors of safety have been calculated by the
* * * * * SIMPLIFIED JANBU METHOD * * * *
The 10 most critical of all the failure surfaces examined
are displayed below - the most critical first
Failure surface No. 1 specified by 37 coordinate points
