Question

The following results were obtained from an oedometer test on a specimen of saturated clay:

54	107	214	429	214	107	54	27	Pressure (kPa):
1.024	1.012	1.001	0.994	1.068	1.144	1.217	1.243	Void ratio:

A layer of this clay 8 m thick lies below a 4 m depth of sand, the water table being at the surface. The saturated unit weight for both soils =19 kN/m3=19 kN/m3. A 4 m depth of fill, unit weight =21 kN/m3=21 kN/m3, is placed on the sand over an extensive area. Determine the final settlement due to consolidation of the clay. If the fill were to be removed some time after the completion of consolidation, what heave would eventually take place due to swelling of the clay?

A layer of this clay 8 m thick lies below a 4m depth of sand, the water table being
at the surface. The saturated unit weight for both soils is 19 kN/m³. A 4m depth
of fill of unit weight 21 kN/m is placed on the sand over an extensive area.
Determine the final settlement due to consolidation of the clay. If the fill were to
3 :
be removed some time after the completion of consolidation, what heave would
eventually take place due to swelling of the clay?
