Question 1 A 5-m-thick clay layer is sandwiched between two permeable sand layers, as shown below. If the compression index Cc=0.4 and the clay is normally consolidated, what is the primary consolidation settlement of the clay layer under surcharge loading of Ao=200 kPa? (Unit: mm) 2.5 m Sand Ydry = 16.5 kN/m³ Groundwater table 4.5 m Sand Ysat = 18.81 kN/m³ Clay Yat = 19.24 kN/m³ :Void ratio, e, = 0.9 LL = 50 Sand
