Refer to Figure 11.45. A square footing, 2 x 2 m in size, supports a column load of 300 kN. The soil characteristics are given in the figure. Field monitoring indicated that the foundation settlement was 19 mm during the first 12 months.
a. Estimate the average stress increase in the clay layer due to the applied load.
b. Estimate the primary consolidation settlement.
c. What is the degree of consolidation after 12 months?
d. Estimate the coefficient of consolidation for the pressure range.
e. Estimate the settlement in 24 months.
