A square column foundation with base of 1.50 m is shown in the figure. It carries an axial load of 490 kN and has its bottom resting on the ground water table located h1 = 1.3 m. below the ground surface. h2 = 0.7 m and h3 = 2.6 m. Compute the increase in pressure in KPa in the clay layer below the center of foundation using the 2:1 method. average |P Dry Sand Wet Sand Clay Soil Properties: Unit Weight of Dry Sand= 15.3 KN/m3 Saturated Unit Weight of Sand = 19.2 KN/m3 Saturated Unit Weight of Clay = 18.7 KN/m3 Compression Index = 0.267 Swell Index = 1/5Cc ✓ I 2 22 h1 h3
