An infinite slope is shown in the figure. The shear strength parameters at the interface of soil and rock are c= 18 kN/m^3 and angle of friction is 25 degrees. Unit weight of the soil is 18.639 kN/m^3. a) If H is equal to 8m and angle of backfill from horizontal is 20 degrees, determine the factor of safety against sliding. b) If angle of backfill form horizontal is 30 degrees, determine the critical height. c) If H = 6m, determine the maximum angle of backfill from horizontal so that the slope is stable.
