Pick - out the INCORRECT assumption of terzaghi’s theory of consolidation of soils.
1
Soil is laterally confined, and the consolidation takes place only in axial direction. Drainage of water also occurs in vertical direction
2
The soil is homogenous and isotropic
3
There is unique relationship between the volumetric strain and the effective stress and this relationship remains constant during the load increment
4
The soil is fully saturated
