technique for generating CIRCULAR surfaces has been specified. <br /> 144 trial surfaces will be generated and analyzed. <br /> 12 Surfaces initiate from each of 12 points equally spaced <br /> along the ground surface between x = 255 . 0 ft <br /> and x = 300 . 0 ft <br /> Each surface terminates between x = 100 . 0 ft <br /> and x = 128 . 0 ft <br /> Unless further limitations were imposed, the minimum elevation <br /> at which a surface extends is y = . 0 ft <br /> 7 . 0 ft line segments define each trial failure surface. <br /> --- -- ---------------- <br /> ANGULAR RESTRICTIONS <br /> ----- -- - --- ---------- <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 (slope angle - 5 . 0) degrees <br /> Factors of safety have been calculated by the <br /> * * * * * SIMPLIFIED BISHOP METHOD <br /> The most critical circular failure surface <br /> is specified by 24 coordinate points <br /> Point x-surf y-surf <br /> No. (ft) (ft) <br /> 1 255 . 00 78 . 00 <br /> 2 248 . 17 76 . 49 <br /> 3 241 . 28 75 . 20 <br /> 4 234 . 37 74 . 14 <br /> 5 227 . 41 73 . 31 <br /> 6 220 . 44 72 . 71 <br /> 7 213 .45 72 . 34 <br /> 8 206 . 45 72 . 20 <br /> 9 199 . 45 72 . 30 <br /> 10 192 . 46 72 . 62 <br /> 11 185 . 48 73 . 18 <br />
