A critical failure surface searching method, using a random technique for generating CIRCULAR surfaces has been specified. 1000 trial surfaces will be generated and analyzed. 100 Surfaces initiate from each of 10 points equally spaced along the ground surface between x = .0 m and x = 10.0 m Each surface terminates between and
x = x =
30.0 m 50.0 m
Unless further limitations were imposed, the minimum elevation at which a surface extends is y = 5.0 m

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 := Upper angular limit :=
-45.0 degrees (slope angle - 5.0) degrees
Factors of safety have been calculated by the : * * * * *

A critical failure surface searching method, using a random technique for generating CIRCULAR surfaces has been specified. 1000 trial surfaces will be generated and analyzed. 100 Surfaces initiate from each of 10 points equally spaced along the ground surface between x = .0 ft and x = 10.0 ft Each surface terminates between and
x = x =
40.0 ft 60.0 ft
Unless further limitations were imposed, the minimum elevation at which a surface extends is y = .0 ft

3.0 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 := Upper angular limit :=
-45.0 degrees (slope angle - 5.0) degrees
