Question $1[30$ Marks$]$

Figure Q$1$ shows a soil profile, with $1$ m capillary fringe in the top sand layer which makes

the one metre thick strip of the sand layer above the water table to be fully saturated. The

soil has a $50$ kPa load imposed at the ground surface.

Figure Q$1$

$($i$)$ Plot total stress, pore water pressure and effective stress with depth for the whole soil

profile.

$($ii$)$ Plot total stress, pore water pressure and effective stress with depth for the whole soil

profile immediately a $50$ kPa load is placed on the soil.

$($iii$)$ Plot total stress, pore water pressure and effective stress with depth for the whole soil

profile a long time after the load was placed and when all excess pore water pressures have

dissipated.
