Using the below information answer Questions 12 to 14: A square foundation, 2.5 x 2.5 m in size, supports a column load of 478 kN. The soil characteristics are given in the figure below. 478 kN 1.5 m 2.5 m x 2.5 m Yd=16 kN/m³ GWT 1.75 m 3.5 m Sand Clay Ysat 18.8 kN/m³ w=19% G₁ = 2.71 LL=37 σ' = 65 kN/m² C₁ = 1/5 Cc C=0.243 Ysat 20.88 kN/m³ Calculate how much would be the stress increase (Aσ, kN/m²) in the the middle of the clay layer due to the applied load. Question 13 Find the σ'o (kN/m²) at the middle of the clay layer. Question 14 Estimate the primary consolidation settlement of the clay soil in millimeters (mm).
