Figure As 1 shows rigid walls of height Ho with different geometries. Sketch the distribution of lateral earth pressures on each wall; indicate the location and direction of the resultant lateral force. Show on your diagram what other forces act on the wall, for example, the weight of the wall (Ww) and the weight of the soil (Ws). You should consider two cases of soil-wall friction: (1) Type equation here. δ > 0 and (2) δ = 0.
