For the slope shown in the figure below (Figure is not to scale), determine the factor of safety against sliding along the circular slip surface AC. The soil information is as follows: 7-19 kN/m, c'=31 kN/m, p=24 (a) Use the ordinary method of slices (10 points); (b) Use the Modified Bishop's Method (10 points); (c) Explain the differences between the two methods (4 points); and (d) Describe the general procedure for slope stability analysis (6 points). *Divide the slope into 7 slices, 6 of them covering the sloped face, having equal width. *Please list the values of W and a for each slice. 30 as W 27 m 7.5 m B+C W a, d 21 m Slice W Number (kN/m) 1 59.8 2 3 4 5 6 7 786.6 1162.8 1162.8 1043.1 718.2 177.9 a 111 (degree) (m) 70 34 38 24 12 0 -8 4.386 10.204 7.614 6.564 6.135 6 4.848 For the slope shown in the figure below (Figure is not to scale), determine the factor of safety against sliding along the circular slip surface AC.
