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:
(a) The consolidation settlement of the clay layer (using 4
equal layers in your calculation), and
(b) The time (in days) for this consolidation...

Problem 3 In a laboratory consolidation test on a representative sample of cohesive soil, the original height of a double-drained sample 50% consolidation was 5 min. The laboratory sample was taken from a soil layer which is 15 m thick in the field, doubly drained, and subjected to similar loading. How long will it take until the layer consolidates 50 %? b. If the final consolidation settlement is predicted to be 20 cm, how long will it take for a...

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
