A square footing, 1.7 m x 1.7 m, is to be founded at a depth of 1.4 m below the ground surface of a deep clayey sand stratum. The saturated unit weight of the soil is 17 kN/m. Based on drain triaxial tests, the soil parameters are c' = 7 kPa and ø' = 25°. The ground water table was found at the surface level. The foundation is to carry a permanent load of 280 kN and a variable load of 210 kN. Determine the ultimate bearing capacity for the footing using Terzaghi's equation. Applying trie traditional approach, establish if this footing can be considered safe, that is, if the factor of safety is equal or greater than 3.

Question
A square footing, 1.7 m x 1.7 m, is to be founded at a depth of 1.4 m below the ground surface of a
deep clayey sand stratum. The saturated unit weight of the soil is 17 kN/m3. Based on drain triaxial
tests, the soil parameters are c' = 7 kPa and ø' = 25°. The ground water table was found at the
surface level. The foundation is to carry a permanent load of 280 kN and a variable load of 210 kN.
Determine the ultimate bearing capacity for the footing using Terzaghi's equation.
Applying trie traditional approach, establish if this footing can be considered safe, that is, if the
factor of safety is equal or greater than 3.
