A square column foundation with base of 1.40 m is shown in the figure. It carries an axial load of 481 kN and has its bottom resting on the ground water table located h1 = 1.4 m. below the ground surface. h2 = 0.8 m and h3 = 2.6 m. Compute the settlement of the clay layer in millimeter caused by primary consolidation if the preconsolidation pressure of the clay is 103 KPa.
