A retaining wall is 10m high, and the back surface of the wall is vertical and smooth. The wall is retaining two layers of soil, which is horizontal on the surface and applied the uniform load of q=20kPa. The upper layer is the medium sand, with the unit weight y₁ = 18.5kN/m³, the internal friction angle ₁ = 30°, and the layer thickness h = 3m; The lower layer is the coarse sand, with unit weight 72 = 19.0kN/m³, the internal friction angle ₂ = 35°; Calculate the active earth pressure and the total active thrust acting on the wall..
