In the figure below, the natural soil profile consists of sand
overlying clay overlying sand overlying bedrock. A
water table is present 1 m beneath the surface of the natural
ground. If 4 m of consistent fill material (γfill = 15
kN/m3) was placed on top of this soil profile that covered a
large area, determine:

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...

Problem 1 A deposit of Swedish clay is 15 m thick drained at both top and bottom. The coefficient of consolidation for the clay layer was estimated to be 1 x 10 cm/sec from laboratory test. The ultimate consolidation settlement (Sc) was calculated under the applied load in the field and was found 80 cm. Find the following: a) How long would it take for settlement of 40 cm and 70...

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
soil...

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.

7) (Total 20 pts) The figure shows a 20 m thick layer of normally consolidated clay (Y -18.6 kN/m3) that is one-dimensionally loaded by Δσ,-50kPa. The clay layer is below a 3 m thick layer of granular fill (y = 19.6 kN/m3), and a dense, compacted glacial till (impermeable) underlies the clay. The water table is located at the top of the clay layer. A 1-D consolidation test is performed on a 2.20 cm thick, doubly drained specimen from the...
