Question

In laboratory consolidation tests on a clay specimen (drained on both sides), the following results were obtained:
• thickness of clay layer = 25 mm
• σ'₁ = 50 kN/m² , e₁= 0.75
• σ'₂ = 100 kN/m² , e₂= 0.61
• time for 50% consolidation (t₅₀) = 3.1 min
Determine the hydraulic conductivity of the clay for the loading range.
