sit o SIT O. A square footing 3 x 2 m carries a column load of 3500 kN resting 0.60 m below theground on the sand layer. The sand layer is 2.4 m thick with a 1.2 m clay layerunderneath it. The ground water table is 1.2 m below the ground surface. The sandhas dry and saturated unit weights 17.31 kN/m³ and 18.10 kN/m² respectively. Theclay has G=2.50, LL=49% and w=68%.a. Compute the preconsolidation pressure if the overconsolidated ratio is 2.0.b. Compute the total effective stress at the center of the clay layer.c. Calculate the settlement due to consolidation of the overconsolidated clay layer.

To Find :- Preconsolidation pressure Total effective stress at center of clay Settlement of clay
