Question: A 3 m thick saturated clay layer is overlain by a 4 m thick sand layer and is underlain by rock. The unit weight of

A 3m thick saturated clay layer is overlain by a 4m thick sand layer and is underlain by rock. The unit weight of sand and clay are 17kN/m3 and 18kN/m3 respectively. The clay has a liquid limit of 53% and a void ratio of 0.80. A concentrated load of 2000kN is applied on the ground surface. Compute the probable consolidation settlement of clay.
