Question

The total, neutral and effective vertical stresses (in t/m${}^2$) at a depth of 5 m below the surface of a fully saturated soil deposit with a saturated density of $2t/m^3$ would, respectively, be

• A. 5, 5 and 10
• B. 5, 10 and 5
• C. 10, 5 and 10
• D. 10, 5 and 5

Answer 1

The correct option is D 10, 5 and 5

$Totalstress,\sigma =2\times 5=10t/m^2$
$Neutralstress,u=1\times 5=5t/m^2$
$Effectivestress,{\sigma }^{\prime }=\sigma -u=10-5=5t/m^2$
