A rectangular footing (0.75m∙0.75m), embedded 0.5 m, carries a downward column load of 200 kN. The footing is supported on an overconsolidated clay with the following properties:

Cr = 0.05 e = 0.7 OCR = 2.0

PI = 55 cu = 200 kPa ϒsat = 16.2 kN/m3

The ground water table is at a depth of 1.0 m below the ground surface.

a) Calculate the primary consolidation settlement for this footing.

b) Is the calculated Sc within tolerable limits?

Hint: This clay deposit is very deep. Assume that the portion (or thickness) of the clay layer that will consolidate is between z = Df and z = Df + 2B.
