Question

In a saturated soil deposit having a density of 22kn/m3, the effective normal stress on a horizontal plane at 5m depth will be

Answer 1

The answer is 60 KPa.

Explanation:

Effective stress $= \gamma_{sub} \times depth$

$\gamma_{sub}=\gamma_{sat}-\gamma_{w} =22-10= 12 \ \frac{KN}{m^3} \\\\\bar{{\sigma}}=\gamma_{sub}\times depth = 12\times5= 60 \ KPa$
