$($a$)$ Calculate the total unit weight $()$ of the soil using the measurements from the

oedometer sample.

$($b$)$ Determine the initial void ratio $(e_0)$ at the start of the test by assuming full saturation of

the sample.

$($c$)$ Determine void ratios measured and recorded at the end of each loading stage of the

oedometer test.

$($d$)$ Plot a compression curve showing the relationship between void ratio $($e$)$ and vertical

effective stress $({}_v^{\text{'}}).$ Note that ${}_v^{\text{'}}$ is on a logarithmic scale.

$($e$)$ Calculate the initial and final vertical effective stresses at the mid$-$height for each of the $5$

sub$-$layers within the soft clay deposit, considering each layer's thickness of $2m.$

$($f$)$ Based on the compression curve, present the initial and final void ratios of each sub$-$

layer while determining the reduction of sub$-$layer thickness and final settlement of the

embankment.
