Question

A layer of clay 2 meters thick will settle 44 mm under an
applied load. Calculate how long it will take to achieve 30% of the
total settlement if the coefficient of consolidation is 0.00026
cm^{2}/s and the clay layer can drain from the top only.
Provide your answer in units of days as a whole number.

Answer #1

To achieve 30% of total settlement it will take 126 days.

A layer of clay, 4 meters thick will settle a total of 57 mm
under a new applied load. Determine how much settlement will occur
within the first year if the coefficient of consolidation is 0.07
cm2/min and the soil can only drain from the top.
Provide your answer in millimeters as a whole number.

A 10-ft-thick silty clay layer is subjected to a load that
results in total primary consolidation settlement of 0.85 inches.
The clay is sandwiched between two sand layers and has an initial
void ratio of 0.76, a coefficient of compression of 0.45, a
coefficient of recompression of 0.07 and a coefficient of
consolidation of 0.034 in2 /year. Calculate the settlement at the
end of 2 years and determine the time in days for 0.60 inches of
settlement.

The ultimate consolidation of a 13-ft thick single-drained clay
layer (cv = 0.1 ft2/day) was calculated to be
0.813 feet.
a. What is the average degree of consolidation for the clay
layer when the settlement is 2 inches?
b. If the average value for cv for the pressure range is 0.003
cm2/second how long will it take for 50% settlement to
occur? (be careful on the units)
c. If the 17 ft clay layer is drained on one side, how...

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...

Consider a clay layer that is 1 m thick. The clay has a
compression index of 0.35, a swell index of 0.07, a permeability of
4 x 10-7 cm/sec, a preconsolidation pressure of 172 kPa and a
coefficient of consolidation of 2.7 x 10-4 cm2/min. The initial
effective stress at the midpoint of the layer is 140 kPa, and the
soil has a void ratio of 1.01. The stress is increased to 200 kPa.
The soil is drained above and...
