• 1 <br />5 1200.00 280.00 <br />A Critical Failure Surface Searching Method, Using A <br />Random <br />Technique For Generating Circular Surfaces, Has Been <br />Specified. <br />30 Trial Surfaces Have Been Generated. <br />10 Surfaces Initiate From Each Of 3 Points Equally <br />Spaced <br />Along The Ground Surface Between X = 115.00 ft. <br />and X = 215.00 ft. <br />Each Surface Terminates Between X = 300.00 ft. <br />and X = 400.00 ft. <br />Unless Further Limitations Were Imposed, The Minimum <br />Elevation <br />At Which A Surface Extends Is Y = 60.00 ft. <br />• 10.00 ft. Line Segments Define Each Trial Failure <br />Surface.. <br />Restrictions Have Been Imposed Upon The Angle Of <br />Initiation. <br />The Angle Has Been Restricted Between The Angles Of <br />-25.0 <br />And .0 deg. <br />1 <br />Following Are Displayed The Ten Most Critical Of The <br />Trial <br />Failure Surfaces Examined. They Are Ordered - Most <br />Critical <br />First. <br />* <br />* * Safety Factors Are Calculated By Spencer's Method <br />• Failure Surface Specified By 29 Coordinate Points <br />
