A reinforced concrete cantilever retaining wall is 200 mm thick with a base of 300 mm thick. The retained height is 3500 mm with a soil cover of 500 mm, toe = 450 mm and heel = 1600 mm. The backfill behind the wall will be subjected to an imposed load of 2.5 kN/m². A geotechnical engineer provided the following soil parameters: Unit weight of soil = 21 kN/m² • Angle of internal friction = 30° • Allowable bearing pressure = 200 kPa • Friction co-efficient = 0.32 The retained soil (backfill) will be well-drained and the soil in front of the wall will be well compacted and may be used to offer passive resistance to sliding. 2.1 Check the stability of the wall against overturning, sliding and ground pressure.[42] 2.2 Design suitable steel reinforcement for flexural in the stem at the ultimate limit state using grade 25/26 concrete and high tensile steel reinforcement.
