A rigid shallow foundation $1\mathrm{.}25$ m $\backslash$times $2\mathrm{.}5$ m is shown in Figure below. Calculate the elastic settlement of the foundation.

Given: Df$=1\mathrm{.}25$ m$,$ H$=5$B$,$ q$=200$ kN$/$m$2,$ poison's ratio $=0\mathrm{.}4$

E$1=16000$ kN$/$m$2,$ E$2=20000$ kN$/$m$2,$ E$3=20000$ kN$/$m$2$A rigid shallow foundation $1\mathrm{.}25m2\mathrm{.}5m$ is shown in Figure below. Calculate the elastic settlement of the foundation.

Given: $D_f=1\mathrm{.}25m,H=5B,q=200k\frac{N}{m^2},$ poison's ratio $=0\mathrm{.}4$

$E_1=16000k\frac{N}{m^2},E_2=20000k\frac{N}{m^2},E_3=20000k\frac{N}{m^2}$
