Question
For a laboratory consolidation
test on a clay specimen (drained
both sides), the following were
obtained.
Thickness of the clay layer =
25mm
o_1 = 200KN/m^2
o'2 = 400KN/m^2
e_1 = 0.73
e_2 = 0.61
Time for 50% consolidation (t_50
= 2.8min: From table U = 50%, Tv
= 0.197
%3D
Determine the hydraulic
conductivity (in cm/sec) of the
clay for the loading range.
