Solution

The correct option is B 1 and 2 only
Secondary consolidation continues much beyond primary consolidation and occurs at a much slower rate. It occurs at a constant effective stress and is not associated with the dissipation of excess pore water pressure. It does not obey Terzaghi's 1 - D theory.

Q. Consider the following statements:
Theory of consolidation predicts settlement due to primary consolidation; it cannot include settlement due to initial compression nor due to secondary consolidation. The happens because of the following assumptions made by the theory:Which of these statements are correct?

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. The one dimensional theory of consolidation proposed by Terzaghi derives its name due to fact that

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.

Q. Directions : Each of the next items consists of two statements, one labelled as the 'Statement (I)' and other as 'Statement (II)'. Examine these two statements carefully and select the answers to these items using the codes given below:

Codes :

Statement (I) : Rate of settlement of a consolidating layer depends upon its coefficient of consolidation, which is directly proportional the permeability and number of drainage paths available.

Statement (II) : The excess hydrostatic pore pressure is relieved fast in soil of higher permeability, in turn, depending on the number of drainage paths available in the consolidating layer.
