How to solve

Problem $2(10$ points$)$

For the previous problem, estimate the primary consolidation settlement if the soil layer is replaced by a $10$ ft clay layer with the same unit weights, same water table depth, $c_c=0\mathrm{.}05,c_s=0\mathrm{.}15,e_0=0\mathrm{.}8,$ and preconsolication pressure of $400$ psf $.$

Use the equations below for calculating the stress increase in the clay layer.

$=q_o{I}_c$

${}_{gv(\frac{H_2}{H_1})}=\frac{{}_z+4{}_m+{}_b}{6}$
