Problem $5(35$ pts$)$

Figure $5$ shows a section of a foundation supporting a square footing of an industrial building. The column of the hoosng supponts $375$ kjp load as shown in Figure $5.$ The dimension of the square footing is $5ft5ft.$ The soil profile is also shown in the figure. The water table is at the base of the foundation. Consolidation test resulls of the soilf fom the clay layer are given below;

Preconsolidation Pressure, ${}_c=1368\mathrm{.}6$ psf

Compression index, $C_c=0\mathrm{.}396$

Swelling index, $C_s=0\mathrm{.}04$

initial Void Ratio, $e_0=0\mathrm{.}8$

Calculate the primaryconsolidation settlement of the square footing $($@center$)$ due to the given loading condition of the $5ft5$ f square footing. Determine stress increaseusing $m$ &n method $($Boussinesq Case$)$
