-- WARNING -- WARNING -- WARNING -- WARNING -- (# 48) ***************************************** * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ** Negative effective stresses were calculated at the base of a slice. This warning is usually reported for cases where slices have low self weight and a relatively high "c" shear strength parameter. In such cases, this effect can only be eliminated by reducing the "c" value. ***************************************** * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ** USER SELECTED option to maintain strength greater than zero Factors of safety have been calculated by the : SIMPLIFIED BISHOP METHOD The most critical circular failure surface is specified by 12 coordinate points Point x -surf y -surf No. (ft) (ft) 1 141.67 16.67 2 146.33 18.47 3 150.82 20.66 4 155.11 23.24 5 159.15 26.18 6 162.93 29.46 7 166.40 33.05 8 169.55 36.94 9 172.36 41.08 10 174.79 45.44 11 176.84 50.00 12 176.85 50.04 * * ** Simplified BISHOP FOS = 1.169 * * ** The following is a summary of the TEN most critical surfaces Problem Description : Bucklen Pit FOS Circle Center Radius Initial Terminal Resisting (BISHOP) x -coord y -coord x -coord x -coord Moment (ft) (ft) (ft) (ft) (ft) (ft -lb) 1. 1.169 123.25 71.32 57.68 141.67 176.85 1.089E +06 2. 1.172 105.47 97.76 88.80 141.67 180.37 1.770E +06 3. 1.175 124.90 67.86 53.87 141.67 175.70 9.525E +05 4. 1.184 127.26 65.99 51.38 141.67 176.09 9.983E +05 5. 1.203 124.48 54.51 44.16 137.22 166.67 6.158E +05 6. 1.215 130.68 57.18 45.43 137.22 175.48 1.380E +06 7. 1.227 128.16 68.50 57.00 137.22 182.07 2.326E +06 8. 1.239 133.31 59.27 47.21 137.22 179.58 1.919E +06 9. 1.267 123.06 48.69 39.13 137.22 159.39 2.762E +05 10. 1.303 139.08 48.95 28.71 146.11 166.84 2.295E +05 * * * END OF FILE * * * Page 5of15
