Q.3) A soil profile consists of a sand layer 2m thick, whose top is the ground surface, and a clay layer 3m thick with an impermeable boundary located at its base. The ground water table is at the ground surface. A widespread load of 150kPa is applied at the ground surface. Assume that the soil is in a normally consolidated state. Calculate the consolidation settlements at 3 months, 6 months and 2 years if the load is increased linearly to 100kPa over 6 months. 3, Yclay(sat) = 17 kN/m³, eo= 1.5 Cc=0.5 c=5.5m²/year Ysand(sat) 21 kN/m³.
