A 5.1 m thick clay soil with a current overburden pressure of 89 kPa is going to experience an additional stress of 89 kPa after a new structure is built. If it was determined that the clay is normally consolidated has an initial void ratio of 1.2, a recompression index of 0.07, and a compression index of 0.47. Determine the total amount of settlement that is expected to occur. Provide your answer in meters to 3 decimal places.
Knowing that the compression index, Cc = 0.333, and the preconsolidation pressure s’c = 140 kPa with an initial void ratio e0 = 0.85 for a H = 3 m thick clay layer which is subjected to a new loading for an embankment resulting in a stress increase to 200 kPa; what is the expected consolidation settlement? Provide answer below in meters (m).
