45.) A retaining wall supports a horizontal backfill that is composed of two types of soil. First layer: 5.91 meters high, Unit weight of 17.26 kN/m3, coefficient of active pressure of 0.291 Second layer: 5.36 meters high, Unit weight of 18.85 kN/m3, coefficient of active pressure of 0.301 Determine the distance of the total active force measured from the bottom of the wall. Round off to three decimal places.

Determine the total active thrust, in kN/m, for a retaining wall (height 5.12 m.) with horizontal backfill given the following properties: Unit weight = 17.79 kN/m3, Angle of internal friction = 30°, Cohesion = 11.71 kPa, and Surcharge = 9.33 kPa.

A retaining wall 7 m high, with its back face smooth and vertical. It retains sand with its surface horizontal. Using Rankine’s theory, determine the active earth pressure at the base when the backfill is submerged with water table at the surface. Take γ=18 kN/m^3 ,ϕ=30°, γ_sat=21 kN/m^3.
