Section $11\mathrm{.}2$ Consolidation Settlement versus Time Computations

$11\mathrm{.}8$ Consider the proposed fill and soil profile shown in Figure $11\mathrm{.}5,$ except replace the sandy silt strata with an impervious bedrock. Using the simplified solution, compute the consolidation settlement at $t=15$ years after placement of the fill. The ultimate consolidation settlement is $0\mathrm{.}50$ m $.$ Do not apply any correction for the construction period.

$11\mathrm{.}9$ For the situation described in Problem $11\mathrm{.}8,$ how long will it take to reach $95\%,98\%,$ and $99\%$ of the ultimate consolidation settlement? Use the simplified method. The owner has asked you "How long will the settlement take?" How would you reply?$11\mathrm{.}2$ Consolidation Settlement Versus Time Computations
