Laboratory tests were performed on clay samples collected from Figure 1, the following parameters were measured and calculated: eo = 1.05 Cc = 0.325 Cr = 0.0320 m = 10.5 mr = 105 Determine the settlement of the clay layer after the placement of the gravel fill, see the above figure for reference: a) using Terzaghi method assuming that the mid-stresses to be representative of the entire layer. b) using Janbu method by dividing the clay layer into 3 equal parts. c) explain any differences between the two procedures used in (a) and (b), in other words, would you expect the same results.

Two undisturbed clay samples were taken from the middle of the
overconsolidated and normally consolidated clay layers in the soil
profile shown. The water table is at the top of the
overconsolidated clay layer. Consolidation tests were carried out
on the two samples and the results are summarized in the table
below. Assume that the bulk, dry, and saturated unit weights of the
sand are 16 kN/m3, 16 kN/m3 and 19
kN/m3, respectively. The specific gravity of the clay
