Specimen height is $25\mathrm{.}4mm,w_n=32\mathrm{.}5\%,{}_d=1\mathrm{.}45M\frac{g}{m^3}.$ Sample is from a depth of $-11\mathrm{.}5m.$

$8\mathrm{.}19$ At the site where the sample of Problem $8\mathrm{.}18$ was taken; the soil profile consists of about $6\mathrm{.}5m$ of sand and rubble fill and then $9\mathrm{.}1m$ of clay. The water table is about $1\mathrm{.}8m$ below the ground surface. Average densities of the sand and rubble fill are $1\mathrm{.}45M\frac{g}{m^3}$ above the water table and $1\mathrm{.}70M\frac{g}{m^3}$ below the water table. Estimate the consolidation settlement if the average stress increase in the compressible layer is $($a$)50$kPa, $($b$)100$kPa, and $($c$)250$kPa. Use both Eq$.(8\mathrm{.}19)[$or Eq$.(8\mathrm{.}17)]$ and your percent compression plot from Problem $8\mathrm{.}18,$ and compare the results. Comments?
