In a T-shaped Retaining wall, the main reinforcement on the toe is provided at
- ATop face parallel to the wall
- BTop face perpendicular to the wall
- CBottom face parallel to the wall
- DBottom face perpendicular to the wallCorrect
Solution
Concept
Toe slab behaves as a cantilever
Step-by-step solution
1. The soil pressure pushes the toe upward, so it bends like a cantilever with tension at the bottom. 2. The main bars run across (perpendicular to) the wall.
Explanation
Tension at the bottom face, bars span the toe projection.
Why the other options are wrong
Top-face reinforcement is for the heel.
Shortcut
Toe → bottom; heel → top.
Correct answer: D) Bottom face perpendicular to the wall
