Question
In the laboratory test on a clay sample of
thickness 25mm, drained at top only, 50%
consolidation occurred in 11 minutes. Assume
= 0.197, T = 0.405. Find the time required
for the corresponding clay layer in the field of 3m
thick and drained at top and bottom to undergo
50% consolidation. Also, find the time required to
undergo 70% consolidation.
