The average soil profile obtained from test pits at a site of a proposed building whose foundation

is to be placed at a depth of $2\mathrm{.}5$ m $.$ The ground water table is at a depth of $3\mathrm{.}5$ m $.$ It is estimated

that the additional stress on the clay layer due to the weight of the building will be $150K\frac{N}{m^2}$ at

top of the clay and $70K\frac{N}{m^2}$ at bottom of the clay. The following results were obtained from a

consolidation test
