P4: A layer of saturated clay 5 m thick is overlain by sand 4.0 m deep. The water table is 3 m below the top surface. The saturated unit weights of clay and sand are 18 kN/m' and 20 kN/m respectively. Above the water table, the unit weight of sand is 17 kN/m. Calculate the effective pressures on a horizontal plane at a depth of 9 m below the ground surface. What will be the increase in the effective pressure at 9 m if the soil gets saturated by capillary, up to height of 1 m above the water table?
