$($Geotechnical Engineering II$)$ Problem $1$:

Calculate the pressure of the mat foundation on the soil under A$,$ B$,$ C$,$ D$,$ and E$,$ assuming a rigid foundation and

do not ignoring the weight of foundation. The thickness of foundation is $0\mathrm{.}8m$ and it is placed at a depth $($D$)$ of

$1\mathrm{.}0m$ below the ground surface. Concrete unit weight is $23\mathrm{.}6k\frac{N}{m^3}.$
