The Consolidation Time of a Soil Sample

Answer: E. All the above.

The consolidation time of a soil sample increases with increasing compressibility, decreases with increasing permeability, increases rapidly with increasing size of soil mass, and is independent of the magnitude of the stress change.

Solution

The consolidation time of a soil sample is the time which is required for the dissipation of the excess pore water pressure upto a certain limit. Consolidation time depends on the coefficient of consolidation. For a soil sample consolidation time refers to the time required for the soil sample to dissipate excess pore water pressure which depends upon the number of drainage paths.

t =T_vd²/C_v

Where,

t = Time for consolidation, T_v= Time factor, and C_v= Coefficient of consolidation.
