Question

A gravity retaining wall 12m high with interface sloping at an angle of 120 with vertical  retains inclined backfill at angle of 100 with properties c=0, Φ= 300 , γ= 18kN/m3 . Determine and sketch the active earth pressure distribution on the back of the wall and determine the magnitude and line of action of resultant earth pressure. Assume angle of  wall friction is 20​
