Question

Match LIST-I with LIST-II:\[\begin{array}{|c|l|l|} \hline \textbf{LIST-I (Name of Test)} & & \textbf{LIST-II (Used for)} \\ \hline \text{A. Plate load test} & & \text{I. To estimate bearing capacity of granular soil} \\ \hline \text{B. Standard penetration test} & & \text{II. To estimate \textit{in-situ} strength of soft clay} \\ \hline \text{C. Vane shear test} & & \text{III. To identify silt from clay} \\ \hline \text{D. Dilatancy test} & & \text{IV. To estimate bearing capacity for permissible settlement} \\ \hline \end{array}\] Choose the most appropriate match from the options given below:

• A. A - IV, B - III, C - II, D - I
• B. A - II, B - I, C - IV, D - III
• C. A - IV, B - I, C - II, D - III
• D. A - II, B - III, C - IV, D - I

Hint:

Remember: Plate load = settlement, SPT = granular soils, Vane shear = soft clay strength, Dilatancy = identifying silt/clay.

Answer 1

The Correct Option is C

Step 1: Define the objective of each test.
- (A) Plate load test: Determines bearing capacity of soil with respect to allowable settlement $\Rightarrow$ IV.
- (B) Standard penetration test (SPT): Estimates bearing capacity of cohesionless soils $\Rightarrow$ I.
- (C) Vane shear test: Assesses the undrained shear strength of soft cohesive soils $\Rightarrow$ II.
- (D) Dilatancy test: Aids in distinguishing silt from clay $\Rightarrow$ III.

Step 2: Establish the pairings.
\[A \to IV, B \to I, C \to II, D \to III\]

Step 3: Final determination.
The corresponding option is (3).
