Question

Consider the following effects as indicative of complete saturation of a soil sample:

1. Pore water pressure is positive
2. Volume of water to volume of voids is equal to 1..
3. Relative density is equal to 1.

Which of the above statements are correct?

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

Answer 1

The correct option is A 1 and 2

(a)
Degree of saturation of saturated soil is 1.

$S=\frac{V_W}{V_V}=1$

$V_W=V_V$

$I_D=\frac{e_{max}-e}{e_{max}-e_{min}}=1$

i.e., $e=e_{max}$

Hence soil is in densest condition.
