A circular foundation 2m in diameter is shown in the figure below. A normallyconsolidated clay layer 5m thick is located below the foundation. Determine the consolidation settlement of the clay. 1- method 2:1 2- consolidation settlement Cc method

As part of a construction project, a 11 m thick layer of clay is to be loaded with a temporary 5 m thick sand layer. The figure below shows the water-table location, soil unit weights, and the compression curve properties for the clay. Assume the sand layer remains dry. a. Calculate the value of σ′v in the middle of the clay layer (at 5.5 m below the water table) before the sand layer is applied, and after consolidation is complete b. Based on your answer in part (a), and the compression curve characteristics, calculate the settlement that will occur under these conditions. c. How much will the clay layer heave when the 5 m sand layer is removed?
