$.(40\%)$ The allowable settlement for the proposed continuous footing in the figure below is $50mm.$ Using

the classical method and showing all steps and equations, compute its consolidation settlement, ${}_c$ and

determine if it satisfies this criterion. $($The Soil $1$ is silty Clay: $s_u=100$kPa and $=18\mathrm{.}5k\frac{N}{m^3},C_d(1+e)$

$=0\mathrm{.}12,\frac{C_r}{1+e}=0\mathrm{.}025,{}_m^{\text{'}}=200$kPa; Soil $2$:$s_u=120$kPa and $=19k\frac{N}{m^3},\frac{C_d}{1+e}=0\mathrm{.}1,\frac{C_r}{1+e}=0\mathrm{.}02,$

${}_m^{\text{'}}=150$kPa,${}_w=9\mathrm{.}8k\frac{N}{m^3}$; Concrete: ${}_c=23\mathrm{.}6k\frac{N}{m^3},r=0\mathrm{.}85).$

silty Clay

$su=100$KPa

$y=18\mathrm{.}5k\frac{m}{m^3}$

I don't know what o$\text{'}$c value is for the case $2$ formula.I dont know if my steps are correct
