Boring was carried out at a certain subsidence site. Then sample of clay layer was taken without disturbing. Consolidation tests were conducted on this sample. When the consolidation pressure was from 3.2 kg/cm2 to 4.8 kg/cm2 , the void ratio changed from 2.50 to 1.80. The thickness of this clay layer was 5 m. What is the final consolidation settlement of this clay layer?

A sample, 75 mm in diameter and 20 mm high, taken from a clay layer 10 m thick, was tested in an oedometer with drainage at the upper and lower boundaries. It took the laboratory sample 15 minutes to reach 50% consolidation. If the clay layer in the field has the same drainage condition as the laboratory sample, calculate how long it will take the 10 m clay layer to achieve 50% and 90% consolidation. How much more time would...

An embankment will be filled at a site. Before filling the embankment, a soil specimen with a height of 20mm is sampled from the middle of a normally consolidated clay which has a thickness of 4 m. A consolidation test reveals that the soil has a pre-consolidation pressure of 120 kPa, compression index Cc = 0.16, initial void ratio of 0.85. (1) If the settlement of the clay layer is 38.6 mm due to the extra loading from the embankment,...
