20.
The consolidation time for soils
increases with increasing compressibility
decreases with increasing permeability
increases rapidly with increasing size of soil mass
is independent of the magnitude of the stress change.
All the above.

Option A is absolutely correct.

Compressibility means av (coefficient of compressibility) "av" is propertional to "mv", "mv" is inversely proporitonal to "Cv", "Cv" is inversely proportional to "t".

So as av increase mv increase and so cv decreases leading to increase of t i.e consolidation time.

If soil compresses continuously then the consolidation process required to remove air from soil, therefore, consolidation time increase.

If soil doesn't compress then consolidation not required.

"av" is proportional to "mv", "mv" is inversely proporitonal to "Cv", "Cv" is inversely proportional to "t".

So, "t" increases with "av" increased.

E is the correct answer.

t = CV * Tv/d'2.
Cv = k/Av * density.

I think Option A is not correct. Then how it would be D?

Ali Zafar said:   6 years ago
If you see the formula as mentioned above, E is correct.

Pradipto Sarkar said:   7 years ago
All options are correct.

t = (Tv*d^2*Yw*av)/(k*(1+e)).
(1)

How option C and D are correct? Please explain.

Arpita said:   9 years ago
Here, Cv = ((k) * (1+e0)/(Av * Yw)).
