Q1:

A failure wedge develops if a retaining wall

A moves away from the backfill

B moves towards the backfill

C sinks downwards

D stresses equally by vertical and horizontal forces.

ANS:A - moves away from the backfill

When retaining wall moves away from backfill overturning moment is created at the heel. Due to this the heel tries to overturn the backfill thus failure wedge is formed.
