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: $t=$ conditions$).$ Draw the stress diagrams to show the variation of total, pore water pressure and effective stresses with depth for each case.
