Question

Compressibility of a field deposit is

• A. Greater than that shown by a laboratory sample
• B. Smaller than that shown by a laboratory sample
• C. Not at all related to that of a laboratory sample
• D. Equal to that of a laboratory sample

Hint:

In practice, \[ \boxed{ \text{Field Compressibility} > \text{Laboratory Compressibility} } \] due to natural in-situ conditions and soil variability.

Answer 1

The Correct Option is A

Step 1: Recall field and laboratory conditions. A field soil deposit contains natural variations, fissures, stress history, and other in-situ effects that are not completely reproduced in laboratory samples.

Step 2: Compare the compressibility. Because of these field conditions, the compressibility of a field deposit is generally greater than that measured in laboratory tests. Hence, \[ \boxed{\text{Greater than that shown by a laboratory sample}} \] is the correct answer. Therefore, \[ \boxed{(A)} \] is the correct answer.
