Two continuous foundations are constructed alongside each other in a granular soil. Given for the foundation: B = 1.2 m, D_f = 1 m, and center-to-center spacing = 2 m. The soil friction angle ϕ' = 35°. Estimate the net allowable bearing capacity of the foundations. Use FS = 4 and a unit weight of soil, γ = 16.8 kN/m³.
