3.0 ft line segments define each trial failure surface. <br />--------------- <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 :_ (slope angle - 5.0) degrees <br />-- WARNING -- WARNING -- WARNING -- WARNING -- (~ 48) <br />Negative effective stresses were calculated at the base of a slice. <br />This warning is usually reported for cases where slices have low self <br />weight and a relatively high "c" shear strength parameter. In such <br />cases, this effect can only be eliminated by reducing the "c" value. <br />************************************************************************ <br />USER SELECTED option to maintain strength greater than zero <br />Factors of safety have been calculated by the <br />* * * * * SIMPLIFIED BISHOP METHOD <br />The most critical circular failure surface <br />is specified by 30 coordinate points <br />Point x-surf y-surf <br />No. (ft) (ft) <br />1 76.45 35.00 <br />2 79.35 34.24 <br />3 82.28 33.60 <br />4 85.24 33.08 <br />5 88.21 32.67 <br />6 91.19 32.38 <br />7 94.19 32.20 <br />B 97.19 32.15 <br />9 100.19 32.21 <br />10 103.18 32.39 <br />11 106.17 32.68 <br />12 109.14 33.10 <br />
