Question

Consider the following statements:
1. For a saturated soil, Skempton's B-parameter is nearly equal to unity.
2. For an undisturbed sensitive clay, the stress strain curve shows a peak.
3. Interlocking contributes significantly to the shearing strength in case of dense sand.
Which of these statements are correct?

• A. $1,2$ and $3$
• B. $1$ and $2$ only
• C. $2$ and $3$ only
• D. $1$ and $3$ only

Answer 1

The correct option is A $1,2$ and $3$

Dense sands derive their shear strength from interlocking and friction whereas clays derive their shear strength from cohesion. For a saturated soil, skempton's B parameter = 1.
