It's correct.

Lateral earth pressure means horizontal earth pressure, which is proportional to phi in rest, active and also in the passive state both in Rankine's and Columb's theory.

@Rest=1-sin π.
@active=1-sinπ/1+sinπ,

And @passive = 1+sin&π/1-sinπ.

I think C is the right answer.

Here, option B for pressure.

And C for force.

Rahul said:   6 years ago
The magnitude of the lateral earth pressure depends upon the movement of the retaining wall relative to the backfill and upon nature of the soil.

Rishi said:   6 years ago
Answer C is right.

Directly proportional to the square of depth.

Skn said:   6 years ago
The option should be C follow Gupta & Gupta having the same question their also.

Ankur Sharma said:   6 years ago
B is the only correct option.

OPSE AEE said:   6 years ago
The correct answer is C.

I think the answer given here is right,

See the problem here, asks about lateral pressure that is major stress and not active or passive earth pressure intensities. As per Bell's Formula on stresses,

P1 = P3* tan^2(α) + 2C*tan(α)

Hence here P1 i.e. Lateral Stress is directly proportional to the angle of internal friction.
