According to terzaghi, every process involving a decrease in the water content of a saturated soil mass due replacement of water by air is called a process of consolidation.


Consolidation occurs due to one or more of the following factors:

a) Due to external static loads from structures.
b) Due to self-weight of the soil such as recently placed fills.
c) Due to the lowering of the groundwater table.
d) Due to desiccation.
