In Figure 12.24, which shows a vertical retaining wall with a granular backfill, let H = 4 m, α = 17.5º, γ = 16.5 kN/m3, Φ' = 35º, and ẟ' = 10º. Based on Caquot and Kerisel’s solution, what would be the passive force per meter length of the wall?
A 8-meter-high retaining wall, with a perpendicular back, retains the soil with a unit weight of 17.17 kN/m3. The cohesion and the internal friction angle of the backfill were measured as 13 kPa and 20°, respectively. Assume that there is no friction on the wall and the surface of the backfill is horizontal. Calculate the expected active force on the wall and the position of this force.
If a retaining wall 5m high is restrained from yielding, what will be the at-rest earth pressure per meter length of the wall? Given that the backfill is cohesionless soil having angle of 30° and y=18kN/m³. Also determine the resultant force for the at-rest condition.
