Problem $2$

In an oedometer test on a specimen of saturated clay $(G_s=2\mathrm{.}70),$ the applied pressure was increased from

$107$ to $214$kPa and the following compression readings recorded:

TABLE I

After $1440$min, the thickness of the specimen was $16mm$ and the water content was $23\%.$

Determine the values of the coefficient of consolidation $C_v$ and the compression ratios from $($a$)$ the root

time plot and $($b$)$ the log time plot. Determine also the values of the coefficient of volume compressibility

$m_v$ and the coefficient of permeability $k.$
