$1.$ On the stratigraphy shown below, a large extension fill is placed $($it could be considered infinite extension$),$ the fill material has a specific weight of$.24$ kN$/$m$3$ and height of $4$m$.$

a$)$ Determine the settlement that the fill will cause due to the consolidation of the clay layer.

b$)$ Draw a diagram of the total load and pressure load with respect to depth, for the primary consolidation time $($tp$).$ Draw from the surface level to the depth of $6$m$.$

c$)$ Draw a diagram of the pore water pressure with respect to time for the center of the CL stratum. Indicate the extreme values $$of the scheme, both in pressure and time.

Remember that current conditions show unidirectional flow and that is the stability condition
