a smooth vertical back retains sand back s the following properties. c' = 0, y = 1 ide of total thrust against the wall for gi top of wall is restrained against yielding yield, and (c) wall free to yield, water

Design the vertical stem of a T-shaped retaining wall for a height of 3 m above the ground level. The top of the earth retained is surcharged at an angle of 10° with the horizontal as shown in Fig. 18.7. The angle of repose of earth is 29° and its density is 17 kN/m. The safe bearing pressure is 100 kN/m2. Use M25 concrete and Fe 415 grade steel. 150 VERTICAL STEM 3000 1000 J400 TOE 200 Fig. 18.7 T-retaining wall
