Given:
Water level in the lake = 5 m
Saturated unit weight of the lake bed soil (๐›พ') = 20 kN/mยณ
Unit weight of water (๐›พw) = 10 kN/mยณ
Depth below the lake bed = 5 m

To find: Effective vertical stress at 5 m depth below the lake bed

Explanation:

Effective stress is the stress that is transmitted to the soil skeleton and is responsible for deformation.

Total vertical stress (๐œŽv) at a depth of 5 m below the lake bed is given by:

๐œŽv = ๐œŽ' + ๐›พwร—h
๐œŽv = 20 + 10ร—5
๐œŽv = 70 kN/mยฒ

Where h is the depth of water above the soil surface.

Effective vertical stress (๐œŽ'v) is given by:

๐œŽ'v = ๐œŽv - ๐›พwร—h
๐œŽ'v = 70 - 10ร—5
๐œŽ'v = 20 kN/mยฒ

Therefore, the effective vertical stress at 5 m depth below the lake bed is 20 kN/mยฒ, which is option A.
