3. | Calculate the change in total vertical normal stress (o) and in effective stress (6') au a depth of 10 feet in a saturated clay layer if the water table is dropped from the ground surface to a depth of 20 feet below the ground surface. The clay has a water content of 35%, S = 100% and G, = 2.75. Assume that no change in degree of saturation or water content occurs when the water table is lowered. Take into account the capillary stresses generated.
