A 3m × 4m rectangular area carrying a uniform lead 240 kPa is applied to the ground surface having a profile consist of 2 m of silly sand underlain by 3m of clay. The groundwater table is 3m below the ground surface. The sand has a unit weight of 14 kN/m³,the clay has the unit weight of 16 kN/m³ above water table and 20 kN/m³ below water table. a.) determine the approximate vertical stress increment 5m below ground surfaced caused by rectangular footing. b.) determine the total vertical stress at the bottom of the clay layer.
