A layer of saturated clay 5m thick is overlain by sand 4.0 m deep. The water table is 3 below the top surface. The satsurated unit weight of clay and sand are 18KN/m³ and 20kN m3 respectively. Above the water table, the unit weight of sand is 17KN/m³. Calculate the effective pressure on a horizontal plane at a depth of 9 m below the ground surface. What will be the increase in the effective pressure at 9m if the soil gets saturated by capillary, up to height of 1m above the water table? Yw = 9.81kN/m³. %3D

Question
A layer of saturated clay 5m thick is overlain by sand 4.0 m deep. The water table is 3m below the top surface. The satsurated unit weight of clay and sand are 18KN/m³ and 20KNI m3 respectively. Above the water table, the unit weight of sand is 17KN/m³. Calculate the effective pressure on a horizontal plane at a depth of 9 m below the ground surface. What will be the increase in the effective pressure at 9m if the soil gets saturated by capillary, up to height of 1m above the water table? Yw = 9.81KN/m³
