Question

After the hydrostatic pressure is reduced to zero, some compression of soil takes place by the process of _________

(a) effective pressure

(b) load increment

(c) primary consolidation

(d) secondary consolidation

This question was posed to me during an interview.

The query is from Consolidation Process topic in chapter One Dimensional Consolidation of Geotechnical Engineering I

Answer 1

Correct option is (d) secondary consolidation

Explanation: Even after the hydrostatic pressure is reduced to zero, some compression of soil takes place and this is known as secondary consolidation. During secondary consolidation, some of the highly  The effective pressure is the pressure between the soil grains.
