Use 10 kN/m³ for the unit weight of water. Question 10 A site associated with an excavation project is underlain by a 6m thick sand layer with unit weights = 18 and 20 kN/m³. Below the sand layer lies a 6m thick clay layer with unit weights = 19 and 22 kN/m³, void ratio = 1.3. The water table is located at the ground surface. Rock lies below the clay layer. The consolidation parameters obtained from testing a sample obtained from a depth of 9m are: coefficient of consolidation = 0.018 m²/day, compression index = 0.3, recompression index = 0.02, and preconsolidation stress = 210 kPa. A dewatering operation will cause the water table to drop 5m and remain there throughout the project. Calculate the ultimate consolidation settlement of the clay layer. Express your answer in centimeters but write only the numeric answer in the text box.
