A retaining wall .X m high was designed to stabilize a horizontal ground surface. The back of the wall is inclined 20° to vertical direction and can be assumed rough with interface friction angle of X". The soil parameters are = 33°, 7-19kN/m³, 7-21kN/m³. Assume no seepage effects. (a) Draw a diagram to show the given wall dimensions, relevant inclinations and the direction of the active force on the wall. (2 marks) (b) Calculate lateral force on the wall assuming the ground water table is at the ground surface. (5 marks) (c) After a flood, the ground water table rises 0.8 m above the wall top surface on both sides of the wall. Calculate the lateral active force on the wall after the flood. (8 marks) (d) If the weight of the wall is (200+ X) kN/m, is the wall safe against sliding after flooding event? Please show your calculations.
