2. A continuous foundation with a width B = 6 ft is constructed on a layered system consisting of a strong sand over a soft saturated clay. The D; = 8 ft (shown as H₁), H₂ = 4 ft, and the material properties for the clay layers are shown below. Considering a factor of safety of 3, determine the gross allowable bearing capacity (gall) of the foundation. Sand Layer 1 V₁ = 120 lb/ft³ +1'=35° c₁' = 0 psf Clay Layer 2 V₂ = 100 lb/ft³ $2=0° c₂' = 2,000 psf H₁ H2 BxL Layer 1 V1 Φι * V2 Layer 2 Φι
