The soil conditions adjacent to a rigid frictionless retaining wall are shown in the
figure below. A surcharge pressure of 50 kN/m² is applied on the surface of the
backfill.
For Soil A above the water table, c' = 20 kN/m², '= 28°, y = 18 kN/m³
For Soil B below the water table, c' = 0, ' = 38°, y = 20 kN/m³
Calculate the maximum Rankine active earth pressure behind the wall and the
resultant active force per unit length of the wall. Also determine the location of
the resultant force.
