Consolidation Settlement at the center of square footing | Overconsolidated Soil

In this video, we are going to learn how to calculate the consolidation settlement at the center of square footing. We will be also learning how to calculate the stress increase at the center of footing at any specific depth.

Question: A site originally consists of a 3 m deposit of saturated clay overlying bedrock. A 1 m thick fill will be constructed and used to support a 2 m x 2 m square footing. Calculate the ultimate consolidation settlement of the clay if the footing supports a 1000 kN load. Base your calculations on the initial and final stresses at the midpoint of the clay layer ( under the center of the footing). Properties of the clay are as follows: Cc = 0.4, Cr = 0.08, σp' = 50 kPa, w = 0.40, Gs = 2.7
