Question
A clay stratum 8.0 m thick is located at a depth of 6 m from the ground surface. The natural moisture content of the clay is 56% and
G, = 2.75 The soil stratum between the ground surface and the clay consists of fine sand. The water table is located at a depth of
2 m below the ground surface. The submerged unit weight of fine sand is 10.5 kN/m² and its moist unit weight above the water
table is 18.68 kN/m? Calculate the effective stress at the center of the clay layer.
