Considering the soil to be a uniform clay layer, estimate the primany consolidation settlement due to the foundation load. Given: P$=150$kN; B$=3$m; L$=3$m; Df $=1\mathrm{.}5$m; H$=8$m; e$=0\mathrm{.}7$; Gs$=2\mathrm{.}72$; and $LL=42.$ Assume that the clay is nornally consolidated, and the groundwater table is at the foundation level. Use change in pressure $=$ P$/$BL

us$=$ Poisson's Ratio

$E_5=$ modulus of elasticity
