Consider a clay layer with a thickness of 36 meters and a Ccɛ = 0.2 and a Crɛ = 0.02. A circular tank 20 meters in diameter transfers a surface stress of qo = 225 kPa. The clay is divided into 12 sublayers of equal thickness. The initial effective stress σ'vo, preconsolidation pressure σ'p, and stress caused by the circular tank Δσv are given by the provided equations. In these equations, z is the depth in meters; r is the radius of the loaded area; and σ'vo, σ'p, and Δσv are in kPa. Calculate the contribution to the total consolidation settlement of the sublayers with midlayer depth of 7.5 meters and 28.5 meters.
