A retaining wall retains 20 m of a backfill, γ = 17.7 KN/m3, φ = 22° with a uniform horizontal surface. Assume the wall interface to be vertical. The water table lies at a depth of 6 m from the top and the saturated unit weight of the backfill material is 19 KN/m3. If the backfill surface carries a uniformly distributed load (surcharge) of 4.5 KN/m2, Calulate the magnitude and point of application of the total lateral earth force per unit length in rest condition.
