Extracted text: TASK 3 A stability analysis was made for a 12 m height embankment built on soil foundation as shown in Figure 3 using Fellenius method of slices. The ground water level is at the ground of existing foundation soil. Calculate the fctor of safety of the slope for the given failure surface by constructing 5 slices. (Use actual scale of 0.5 cm :1 m, Width of slice, b = 8 m ). R= 25.2 m 12 m Embankment kN Ø' = 30°, c' = 15 kN/m³ m3' Original Soil kN Ø' = 32, c' = 0 kN/m3 Vb = 20 m3,
