Question $3($from Wood $1990$ E$2\mathrm{.}4)$:

The settlement of a flexible circular foundation on elastic soil is given by: $s=\frac{2qa(1-v^2)}{E}.$

Given that the typical range of the Poisson's ratio for soil is $0\mathrm{.}1,$ determine the ratio $of$ the

immediate $(undrained)$ settlement $to$ ultimate settlement and the ratio $of$ immediate settlement $to$

consolidation settlement for a flexible foundation $on$ a saturated, isotropic, elastic soil.
