Repeat Problem 17.8 with the following: density of soil above the groundwater table, ρ = 1800 kg/m³; saturated soil density below the groundwater table, ρ_sat = 1980 kg/m³; c' = 23.94 kN/m²; ϕ' = 25^ο; β = 1.8 m; D_f = 1.2 m; and h = 2 m.

Data From Problem 17.8

A square footing is shown in Figure 17.23. Determine the gross allowable load, Q_all, that the footing can carry. Use Terzaghi’s equation for general shear failure (F_s = 3). Given: γ = 10⁵ lb/ft³, γ_sat = 11^ο lb/ft³, c' = 0, ϕ' = 35^ο, β = 5 ft, D_f = 4 ft, and h = 2 ft.
