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
