A sample of clay has been taken from 5 m below ground level with the water table at 1.5 m below ground level. The weight density of the clay above and below the water table is sat = 20.7 kN/m3 (i.e., clay will be considered saturated due to capillarity) and the K0 value has been determined as 0.85. Determine the total and effective vertical and horizontal stresses at this depth
