Transcribed Image Text:A laboratory consolidation test on a 25 mm thick normally consolidated clay
specimen showed the following data:
Stress
(kPa)
150
300
Determine:
Void Ratio at end
of consolidation
0.9
0.82
The time required for the specimen to reach 50% consolidation was 5 min.
A similar clay layer in the field, 3.0 m thick, and drained only on one side is subject to
a similar average pressure increase (i.e., ovo 150 kPa and ovo + A0 = 300 kPa).
=
The compression index of the clay
The permeability of the clay
The ultimate consolidation settlement in the field
The time required to achieve 50 mm settlement in the field.
