Problem $5$: Now repeat your analysis the consolidation coefficients of the sample at $20,$ but this

time correct the laboratory consolidation test data for the effects of sample disturbance using the

following steps:

$1.$ Use Casagrande$$s construction to determine $\backslash$sigma c$$ Is the in$-$situ clay overconsolidated?

$2.$ Correct the lab consolidation curve for disturbance to estimate the field consolidation curve

$($i$.$e$.$ Schmertmann construction$).$ The in$-$situ water content of sample $1$ was determined to

be w$0=59\mathrm{.}6\%$ and Gs $=2\mathrm{.}72.$ You may assume the clay was fully saturated. Estimate Cc and

Cr

$3.$ Estimate the total settlement which will occur under the center of a building if the building is

constructed at the ground surface and has a foundation contact pressure $(\backslash$sigma v$)$ of $1400$ psf$.$

Assume that the building is of large lateral extent, like a factory, so the increment of stress is

the same at all depths in the clayTable $1$: Incremental

oedometer test data

Problem $4$: Table $[$shows the results of a laboratory consolidation test based on the sample at $20\text{'}.$

Plot the consolidation test results.

Without correcting for sample disturbance $($i$.$e$.$ Schmertmann construction$)$ determine $C_e$

and $C_r.$
