Design a counter fort retaining wall to retain leveled soil of 5 m height over the ground level. The density of soil is 16 kN/m³ and the angle of repose is 30°. The safe bearing capacity of soil is 160 kN/m². The spacing and thickness of counter forts are 3 m and 400 mm respectively. The base slab may be of 4.5 m wide and 400 mm thick. Depth of foundation is 1.2 m. Use M20 concrete and Fe415 steel. Sketch the reinforcement details.
