Question
Transcribed Image Text:4. A square footing having a dimension of 3 m x 3 m carries an axial load of 1500 kN. The bottom of the
footing is 2 m from the ground surface consisting of a layer of sand overlying a 4 m laye of clay. The
water table is located 2 m below the ground surface.
Dry unit weight of sand = 16.5 kN/m³
Saturated unit weight of clay = 20 kN/m³
Void ratio of clay = 0.80
Liquid limit of clay = 50%
a. Compute the increase in vertical pressure.
b. Compute the overburden pressure (effective pressure) at the midpoint of clay.
c. Compute the primary consolidation settlement.
