Detailed Solution
Download Solution PDFExplanation:
Sensitivity (St):
It is defined as the ratio of the unconfined compressive strength of an undisturbed specimen of the soil to the unconfined compressive strength of a specimen of the same soil after remolding at unaltered water content.
\(S_t={(q_u) \,undisturbed\over (q_u)\,remoulded}\)
Based on the value of sensitivity, natural clay deposits are grouped into the following different categories.
| Sensitivity | Classification |
| 1 | No loss in strength on remoulding |
| 2 - 4 | Soil is normal sensitive |
| 4 - 8 | Sensitive |
| 8 - 15 | Extra sensitive |
| > 15 | Quick |
The correct match is P → 2, Q → 4, R → 1, S → 3. Hence option (1) is correct.
