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 saturated. Take γ=18 kN/m^3 ,ϕ=30°, γ_sat=21 kN/m^3.
Assume that a frictionless retaining wall 15 ft high having a vertical backface supports a sandy soil with a unit weight of 118 pcf and an angle of internal friction of 34°. The soil backfill is level. Calculate the difference in the lateral force imposed onto the wall (per foot of wall length) when the at-rest lateral pressure condition applies compared to when the active lateral pressure condition applies (express the difference as a percentage increase related to the active pressure condition).
A retaining wall supports a horizontal backfill that is composed of two types of soil.

(Solve the following exercise, showing and explaining step by step to its resolution). An 8.50 m high retaining wall is built to support a sandy silt with a volumetric weight of 1850 kg/m3 and an angle of internal friction of 28°. The silt also has a cohesion of 1300 kg/m2. The ground surface is horizontal. The effect of the friction of the wall is neglected. Determine the pressure at the base of the screen.
