Question

A dinilar tark with a diameter $D=34m$ is to be constructed on the ground surface of a unillorm saturated medtum clay, as shown in the figure below. The soil has a unit weight of $20\mathrm{.}2k\frac{N}{m^3},$ and the depth to the ground water table $z_w=3m.$ When the tank is conttructed and tilled, It will have total weight of $270,000kN.$ Point $A$ is located under the center of the tank at a depth, $z=24m.$

Compute the vertical total stress and vertical effective stress at point $A$ at three different moments in time.

$1$ Betere nonstruction of the tank starts

Immediately wifter the tank is placed, but before any consolidation occurs. You may assume the construction of the tank is instantaneous.

$$ A very tong time after the tank has been constructed, after consolidation is complete.
