A clay layer 5 m thick has double drainage. It was consolidated under a load of 127.5 kN/m2. The load is increased to 197.5 kN/m2. The coefficient of volume compressibility is 5.79 x 10^-4 m2/Kn and value of k= 1.6 x 10^-8 m/min. If the test sample is 2 cm thick and attains 100% consolidation in 24 hours, what is the time in days taken for 100% consolidation in the actual layer? a. 67,500 b. 65,000 c. 62,500 d. 60,000

Question
A clay layer 5 m thick has double drainage. It was consolidated under a load of 127.5 kN/m2. The load is increased to
197.5 kN/m2. The coefficient of volume compressibility is 5.79 x 10^-4 m2/Kn and value of k = 1.6 × 10^-8 m/min. If the
test sample is 2 cm thick and attains 100% consolidation in 24 hours, what is the time in days taken for 100%
consolidation in the actual layer?
a. 67,500 b. 65,000 c. 62,500 d. 60,000
