$.$ Problem Statement: given the following soil profile and parameters, please calculate

the total stress, pore water pressure and effective stress at points A$,$ B$,$ C$,$ and D for two

cases: $1)$ before the top $10-$ft thick fill is placed on the existing ground surface; $2)$ after

the top $10-$ft thick fill is placed on the existing ground surface $($consider both short$-$term:

t$=0+$ and long term: t$=\backslash$infty conditions$).$ Draw the stress diagrams to show the variation of

total, pore water pressure and effective stresses with depth for each case.
