: A clay specimen was tested in a laboratory consolidation device, which was 12.7 mm thick and the top & bottom boundaries were drained. A 50% consolidation time on the specimen was obtained as 28.4 minutes, Determine the Following: a- The time for 50% consolidation in the field with a 2.5 m thickness where ‘only the top layer is drained. b- The time for 90% consolidation in the field with a 2.5 m thickness where only the top layer is drained. c- For the same field condition above, find the settlement after 1year, if the final consolidation settlement = 0.0345 m.
