Given: a = 0.25 m b = 0.70 m c = 0.80 m d = 3.5 m e = 6 m f = 0.50 m F’c = 24 MPa Fy = 415 MPa Soil unit weight = 18.8 kN/m3 Concrete unit weight = 24 kN/m3 Active earth pressure coefficient = 1/3 Required strength of the wall, U = 0.7D + 1.7H Where D is dead load and H is earth pressure. Consider per meter strip of wall along its length 1. Calculate the factor of safety against sliding of the retaining wall. Consider coefficient of friction at the base = 0.57. Neglect passive earth pressure at the toe. A. 1.45 C. 1.35 B. 1.60 D. 1.77 2. Calculate the factor of safety against overturning of the retaining wall. A. 2.52 C. 1.53 B. 1.19 D. 0.95 3.
