Part A

A square foundation has a width of 2.0 m. The soil has a friction angle of φ' = 27 and c' = 15 kN/m2. The unit weight of the soil γ = 18 kN/m3. Determine the allowable gross load (kN) on the foundation with a factor of safety of of 3. Assume that the depth of the foundation is 2.0 m and that general shear failure occurs in the soil. Give only the numeric answer (no unit).

Part B

Determine the vertical stress increase (kN/m2) under a 5 m wide flexible strip load at the depth of 4 m and at the distance of 5 m from the center of strip. The load per unit area qo is 325 kN/m2.
