Problem $2$: For the clay layer shown in

the figure determine

The stress increase in the middle of the

clay layer. $($use $2$:$1$ method$)$

The settlement at the middle of the clay

layer, $(OCR=1\mathrm{.}5).$

What is the degree of consolidation for

the clay layer when the settlement is $30$

$mm?$

A field monitoring indicated that after $6$

months the settlement was $20mm,$

estimate the settlement $($in $mm)$ after $5$

years.
