Question
An oedometer (consolidation) test is performed on a normally consolidated clay stratum that is 8.5
feet thick, and it found that the clay's initial voids ratio was e, = 0.8 and its primary compression
index is Cc = 0.28. The in-situ stress at mid-clay layer is p. = 2,650 psf, and the building exerts a
pressure through its mat foundation of 970 psf. The secondary compression index C₂ = 0.02.
The time of completion of the primary settlement is approximately 18 months. What is the total
consolidation of the 8.5 foot clay stratum 5 years after the primary consolidation?
