A square column foundation with base of 1.39 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 = 1.5 m. below the ground surface. h2 = 0.7 m and h3 = 2.4 m. Compute the average increase in pressure in KPa in the clay layer below the center of foundation using the 2:1 method.
