4. The construction of a 10m x 10m square water tank in a residential neighbourhood has been planned. As indicated in Figure below, a 6m thick soft clay layer was discovered between sand layers during site exploration. For laboratory studies, an undisturbed soil sample was obtained in the middle of the soft clay layer. The findings of the laboratory consolidation test are listed below. Pressure, o' (kN/m2) | 25 50 200 400 100 800 Void Ratio, e 1.28 1.22 1.14 1.05 0.95 i. Find the preconsolidation pressure (o'c), Virgin, and Laboratory Compression Index using the information above (Cc). ii. Find the primary consolidation settlements that will occur at the water tank's centre due to compression of the soft clay layer
