Practise $3$

A foundation is to be built on the following layered soil profile. The

foundation will exert a load of $200$ kPa more than the insitu effective

vertical stress. If the soft clay void ratio is $0\mathrm{.}6$ and Cc is $0\mathrm{.}30,$ estimate

the primary consolidation settlement of the soft clay layer if the clay

behaves normally consolidated. Use line sketches to support your

calculations where applicable.
