c) A cantilever reinforced concrete retaining wall with 8 m high, is shown in Figure Q4(c). The wall supports backfill with a horizontal surface. The properties of the backfill are; Ybulk = 19 kN/m³ and ' = 26°. The retaining concrete wall has a unit weight of 24 kN/m³. (CO2:PO3)(C4) i) Determine the total active thrust, and the moment against the reinforced concrete retaining wall. ii) Evaluate the minimum restrained force required, T per meter run in order to achieve stability of sliding equal to 1.5. (Ignore the passive resistance in front of the wall) (16 marks) Ybulk = 20 kN/m³ 0.3 m 12kPa Ybulk = 19 kN/m³ $' = 26° 8 = 22° 2.1 m Figure Q4(c) T kN/m 0.3 m 8m
