A 3 meter-thick layer of clay, with a void ratio of 1.4 and compression index, recompression index, and coefficient of consolidation of 0.35, 0.02, and 0.5 m2/year, respectively, carries an effective overburden pressure of 85 kPa. The clay layer is located between two sand layers. Calculate the change (reduction) in thickness of the clay layer if pressure is increased to 105 kPa considering the following conditions: 1- Clay is normally consolidated. 2- Clay has an OCR of 1.15. 3- Clay has an OCR of 1.25 -Determine the time needed to reach 50% degree of consolidation. -What would be the reduction in thickness after 8 months of the loading increase in case “1”?
