Q.1. (ii) The diagram shown in figure 2 is a 0.550m x 11.000m high reinforced concrete retaining wall. The wall retains 11.000m of sand and is restrained by 6.000 meters of sand, as indicated. The density of the sand changes at a depth of 8.000m below the top of the wall. Given the following soil (sand) parameters: G = 2.6 Both layers = 30° Both layers e = 0.5 Upper Sand (8m) e = 0.45 Lower Sand (3m) Determine the magnitude of passive and active earth pressure on the retaining wall. Assume no partial factors of safety, state any additional assumptions made. Not to Scale 0.550m G.L 5m 8m G.L Sand Sand 3m Toe Figure 2. (10 marks)
