For a normally consolidated laboratory clay specimen drained on both sides, the following are given: σ0’ = 4000 ib/ft² e=1.2 σ0’ + Δσ’= 5000 lb/ft² e=0.9 Thickness of clay specimen= 2in Time for 50% consolidation= 2 min. Determine the hydraulic conductivity (ft/min) of the clay for the loading range. How long (in days) will it take for a 6-ft clay layer in the field(drained on both side) To reach 60% consolidation?

Question
For a normally consolidated laboratory clay specimen drained on both sides, the following are given:
σ0’ = 4000 ib/ft² e=1.2
σ0’ + Δσ’= 5000 lb/ft² e=0.9
Thickness of clay specimen= 2in
Time for 50% consolidation= 2 min.
- Determine the hydraulic conductivity (ft/min) of the clay for the loading range.
- How long (in days) will it take for a 6-ft clay layer in the field(drained on both side)
