PLEASE WORK OUT PROBLEM BY HAND, ON PAPER: A cylindrical oil tank having radius $($r$=3$m$)$ gives surface pressure q$\_(0)=500$kpa.

a$(\backslash$Delta $\backslash$sigma $)$ by the tank at the center and at middle of the

clay layer at a depth of $6$ m $.($Use any theory given in class, provide the reference$)$

b$(\backslash$sigma $\_($p$^(\text{'})))=200$k$($N$)/($m$^(2))$

c$90\%$ of this consolidation?

Take coefficient of consolidation $($C$\_($v$))=0\mathrm{.}01($m$^(2))/()$ year.

d$40\%$ of primary consolidation?
