A sand deposit is 10 m thick and overlies a bed of soft clay. The sand above the ground water table has a degree of saturation of 45%. The ground water table is 3 m below the ground surface. Void ratio of sand deposit is 0.70 and SG = 2.65. Determine the increase in the effective stress at a depth of 10 m below the ground surface when the water table is lowered by 5 m. 117.97 kPa 155.92 kPa 37.95 kPa 87 95 kPa
