A wall of m height retains a backfill of dry granular soil that has a level surface and weighs 20 kN/m³. When there is no surcharge above the fill, the overturning moment caused by the total active pressure at a point at the base of the wall is 125 kN-m/m length of the wall. The specifications permit certain amount of uniformly distributed surcharge but state that surcharge must not increase the overturning moment by more than 50%. What surcharge can be allowed if the angle of wall friction is 20° ?
