Solution:
QUESTION: 3

For a sand having an internal friction of 300, the ratio of passive to active lateral earth pressure will be

Solution:

 will be the ratio of passive to active earth pressure.

QUESTION: 4

The nature of earth pressure above dredge line behind a cantilever sheet pile wall is

Solution:

QUESTION: 5

The critical height of an unsupported vertical cut in a cohesive soil is given by
where, C = unit cohesion
φ = angle of internal friction
γ = unit weight of soil

Solution:

QUESTION: 6

Passive pressure in soil is associated with

Solution:

Passive pressure compresses soil horizontally. It occurs when the retaining wall moves towards the backfill. Active pressure stretches soil horizontally and exerts tensile force in soil layer. It occurs when the retaining wall moves away from the backfill.
