Question

Retraining structures may prove exceptionally successful when?

(a) The ground is too fine

(b) The sliding mass is likely to remain wet

(c) The movement is of deep nature

(d) The sliding mass is likely to remain dry

The question was asked in an internship interview.

My query is from Monitoring and Control of Mass Movements in chapter Mass Movements of Engineering Geology

Answer 1

The correct choice is (d) The sliding mass is likely to remain dry

Best explanation: Retaining structures may prove exceptionally successful where- the ground is neither too fine nor too plastic; the sliding mass is likely to remain dry and the movement is of a shallow nature and limited extent.
