A retaining wall is battered away from the fill from bottom to top at an angle of 15° with the vertical. Height of the wall is 6 m. The fill slopes upwards at an angle 15° away from the rest of the wall. The friction angle is 30° and wall friction angle is 15°. Using Coulomb's wedge theory, explained the total active and passive thrusts on the wall, per lineal metre suppose γ = 20 kN/m3.
