The underground water table is located at $1m$ deep from the ground surface for the clayey soil profile

shown in the figure below. The unit weight of the soil above the GWT is $15k\frac{N}{m^{{?}^{{?}^{?}}}}3$ Below the ground

water table, saturated unit weight is $19\mathrm{.}2k\frac{N}{m^{{?}^{{?}^{?}}}}3$ An undisturbed sample is obtained from the midpoint

of the clay layer and this sample is representative of the entire clay layer. A consolidation test is

conducted on this sample. The result of the consolidation test is given by the following parameters:

preconsolidation pressure, $Oc=200$kPa,$Cr=0\mathrm{.}05,Cc=0\mathrm{.}15$ and $eo=0\mathrm{.}8.$ The rock layer is considered to be

incompressible. A square foundation with a width of $2m$ is going to be constructed. The foundation will

be $0\mathrm{.}3m$ thick, and its bottom will be located at $1m$ depth from the surface. It is expected that the

average load the foundation will carry is approximately $1000kN.$

Calculate the $1-$dimensional consolidation settlement by dividing the clay layer into two sublayers.

Consider that the unit weight of the concrete is $23\mathrm{.}6k\frac{N}{m^{{?}^{{?}^{?}}}}3.$

Question $5$: The underground water table is located at $1m$ deep from the ground surface for

the clayey soil profile shown in the figure below. The unit weight of the soil above the GWT

is $15k\frac{N}{m^3}.$ Below the ground water table, saturated unit weight is $19\mathrm{.}2k\frac{N}{m^3}.$ An

undisturbed sample is obtained from the midpoint of the clay layer and this sample is

representative of the entire clay layer. A consolidation test is conducted on this sample. The

result of the consolidation test is given by the following parameters: preconsolidation

pressure, ${}_{zc}^{\text{'}}=200$kPa,$C_r=0\mathrm{.}05,C_c=0\mathrm{.}15$ and $e_o=0\mathrm{.}8.$ The rock layer is considered to be

incompressible. A square foundation with a width of $2m$ is going to be constructed. The

foundation will be $0\mathrm{.}3m$ thick, and its bottom will be located at $1m$ depth from the surface. It

is expected that the average load the foundation will carry is approximately $1000kN.$

Calculate the $1-$dimensional consolidation settlement by dividing the clay layer into two

sublayers. Consider that the unit weight of the concrete is $23\mathrm{.}6k\frac{N}{m^3}$
