Question: A 2 m wide continuous foundation is placed at 1 m depth within a 1.5 m thick sand layer that is underlain by a weaker

A 2 m wide continuous foundation is placed at 1 m depth within a 1.5 m thick sand layer that is underlain by a weaker clay layer. The soil properties are as follows:

Upper sand layer: unit weight = 18.0 kN/m³, ϕ' = 38°

Lower clay layer: unit weight = 19.0 kN/m³, undrained shear strength = 25 kN/m²

Determine the maximum wall load that can be allowed on the foundation with FS = 3.
