A clay formation having a depth of 4 m. underlies a sand formation having a depth of 3, m. 16.5 kN/m3 and the saturated unit weights of clay and sand are 20.4 kN/m3 and 19.6 kN/m3 respectively. The ground water table is at the interface of the sand and clay. The dry. unit weight of sand is a) Compute the effective stress at the bottom of clay. b) Compute the effective stress at the bottom of the clay if water rises to the ground surface.. Saturated unit weight of sand is 19.6 kN/m3. c) Compute the effective stress at the bottom of clay if water rises 2 m. above the ground surface.
