Question

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.

• A. Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)
• B. Both Statement (I) and Statement (II) are individually true but Statement (II) in not the correct explanation of Statement (I)
• C. Statement (I) is true but Statement (II) is false
• D. Statement (I) is false but Statement (II) is true

Answer 1

The correct option is A Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I)

$T_v=\frac{C_v.t}{d^2}=\frac{k}{m_v{\gamma }_w}.\frac{t}{d^2}$
