Question

Assertion (A) : The rates of settlement of building structures on sandy clay soils are faster compared to those of buildings constructed on clayey soils.

Reason (R) : The rate of consolidation is dependent on the permeability of soils and the permeability of sandy clay is more than that of clayey soil.

• A. both A and R are true R is the correct explanation of A
• B. both A and R are true but R is not a correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A both A and R are true R is the correct explanation of A

Rate of settlement depends upon permeability, drainage conditions (single drained or double drained) and coefficient of volume change as

$\text{Time factor,}{T}_v=\frac{C_{v}t}{d^2}$
