Question $2$:

A$.$ Determine the settlement due to the primary consolidation of the clay layer assuming $Cr=$ Cs$.$ The clay layer is underlain by sand layer.

B$.$ Compute the settlement due to secondary compression of the clay layer after $100$ years if $c_V=1\mathrm{.}2\frac{m^2}{?}$ year and $\frac{c_{}}{c_c}=0\mathrm{.}04.$

C$.$ compute the initial settlement knowing that the modulus of elasticity obtained from unconfined compressive strength test.

Compute stresses at mid depth of each layer for estimating the settlement.

$50$ton$=200lh.$
