7.9
A 3 m thick clay layer (cu 1 = 60 kN/m² and y = 19.0 kN/m³)
is underlain by a weaker clay (c,,= 30 kN/m² and
y = 18.0 kN/m³) to a large depth. A 2.0 m wide square
foundation is placed at 1.5 m depth below the ground level.
Determine the maximum column load that can be allowed on
the foundation with FS = 3.
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/m2, d' = 38° Lower clay layer: unit weight = 19.0 kN/m, undrained shear strength = 25 kN/m2 Determine the maximum wall load that can be allowed on the foundation with FS = 3.
Refer to Figure 5.2 and consider a rectangular foundation. Given: B = 1.5 m, L = 2.5 m, Df = 1.2 m, H = 0.9 m, Φ' = 40º, c' = 0, and γ = 17 kN/m3. Using a factor of safety of 3, determine the gross allowable load the foundation can carry. Use Eq. (5.3).
