A normally consolidated clay specimen drained from both sides is tested in the laboratory, and the following data are given: Time for 50% consolidation = 2 min Thickness of clay specimen = 25 mm ơo' = 150 kN/m? ơ0' + Ao' = 300 kN/m? eo =1.1 ei = 0.9 a- Determine the coefficient of permeability (k) of the clay for the loading range b- How long (in days) will it take for a 1.8 m clay layer in the field (double drained) to reach 60% consolidation?
