GP-DV-EQ.OPT <br />A critical failure surface searching method, using a random <br />technique for generating CIRCULAR surfaces has been specified. <br />9000 trial surfaces will be generated and analyzed. <br />30 Surfaces initiate from each of 300 points equally spaced <br />along the ground surface between x = 234.6 ft <br />and x = 235.0 ft <br />Each surface terminates between x = 325.0 ft <br />and x = 335.0 ft <br />Unless further limitations were imposed, the minimum elevation <br />at which a surface extends is y = .0 ft <br />* * * * * DEFAULT SEGMENT LENGTH SELECTED BY XSTABL * * * * * <br />8.0 ft line segments define each trial failure surface. <br />ANGULAR RESTRICTIONS : <br />The first segment of each failure surface will be inclined <br />within the angular range defined by : <br />Lower angular limit -45.0 degrees <br />Upper angular limit -1.0 degrees <br />************************************************************************ <br />-- WARNING -- WARNING -- WARNING -- WARNING -- (# 48) <br />************************************************************************ <br />------------------------------------------------------------ <br />USER SELECTED option to maintain strength greater than zero <br />------------------------------------------------------------ <br />************************************************************* <br />** Factor of safety calculation for surface # 8870 ** <br />** failed to converge within FIFTY iterations ** <br />** ** <br />** The last calculated value of the FOS was 24.2678 ** <br />** This will be ignored for final summary of results ** <br />************************************************************* <br />Circular surface (FOS= 24.2678) is defined by: xcenter = 269.31 <br />ycenter = 1314.96 Init.
