Two undisturbed clay samples were taken from the middle of the
overconsolidated and normally consolidated clay layers in the soil
profile shown. The water table is at the top of the
overconsolidated clay layer. Consolidation tests were carried out
on the two samples and the results are summarized in the table
below. Assume that the bulk, dry, and saturated unit weights of the
sand are 16 kN/m3, 16 kN/m3 and 19
kN/m3, respectively. The specific gravity of the clay

1. An 8-m thick normally consolidated clay layer is doubly drained as shown below. (This means that a very pervious layer compared to the clay exists on top of and under the clay layer) The embankment applied an average vertical stress increase of 100 kPa to the clay layer. The water table is located at the mid depth of the sand layer. Assume the sand above the water table is dry 0 Pore water pressure, u (kPa) 20 40 60...

The time for 50% consolidation of a 25 mm thick clay specimen (drained at top and bottom) in the laboratory is 150 sec. How long (in days) will it take for a 3 m thick layer of the same clay in the field under the same pressure increment to reach 75% consolidation? There is an impermeable shale layer at the bottom of the clay layer in the field I. 2. Use Figure 1 for the following Compute the vertical effective...
