Question
An undisturbed sample of clay, 24 mm in thickness, is tested in a
consolidometer. The total change in the thickness of the specimen in 4.74 mm when the
applied pressure is 200 kN/m² and 6.13 mm when the applied pressure is 400 kN/m. On
reducing the pressure to zero, the specimen swells to a thịckness of 18.50 mm. The final
water content of the specimen is 32.6% and specific gravity is 2.72.
The clay stratum, 1 m thick, is sandwiched between pervious strata, and is subjected
to an overburden pressure of 200 kN/m². Estimate the probable settlement of a proposed
structure, if due to its construction, the effective pressure at the centre of the clay layer
is expected to be increased to 400 kN/m². don't try to solve this question, otherwise
