Solution

The correct option is A 1, 2 and 3
Initial consolidation or elastic compression due to expulsion of pore air or rapid dissipation of pore water with application of stress. This is significant in non-saturated clays, silts and granular soils. Primary consolidation due to slow expulsion of excess pore pressure over a period of time. Scondary consolidation due to viscous layer around particles resulting in rearrangement of particles.

Q. Assertion (A) : Terzaghi's theory of consolidation considers only primary consolidation.

Reason (B) : Secondary consolidation takes place only at the end of the primary consolidation.

Indicate which of the following expressions gives settlement of the layer

A layer of normally consolidated, saturated silty clay of 1.2 m thickness is subjected to one dimensional consolidation under a pressure increment of 25 kPa. The properties of the soil are: Specific gravity = 2.7. natural moisture content = 40% and compression index 0.45. The initial average effective stress within the layer is 125 kPa. Assuming Terzaghi s theory to be applicable, the primary consolidation settlement is mm

Q. Terzaghi's consolidation theory is applicable to one-dimensional consolidation test
