Question

The specific gravity and in-situ void ratio of a soil deposit are 2.71 and 0.85 respectively. The value of the critical hydraulic gradient is

• A. 0.82
• B. 0.85
• C. 0.92
• D. 0.95

Answer 1

The correct option is C 0.92

We know that,

$i_{cr}=\frac{G-1}{1+e}=\frac{2.71-1}{1+0.85}$

$=0.92$
