Bearing Capacity Flood- Proof and Frost Proof: Flood-Proof Infrastructure

Question 1

What is flood-proof infrastructure?

Answer 1

Infrastructure designed to resist and recover from flooding with minimal damage.

Question 2

How can roads be made flood-resistant?

Answer 2

1. Use flexible pavement materials (e.g., cement with additives).
2. Avoid fine particles in gravel (prevents erosion).
3. Ensure proper drainage systems.

Question 3

Why is it important to avoid mixing fine particles with gravel?

Answer 3

The fines will wash out during flooding, creating voids and structural failure.

Question 4

How do third-world countries manage flood risk differently?

Answer 4

• Buildings on stilts, but roads remain vulnerable.
• Focus on strategic stabilization of major roads and intersections.

Question 5

What was the Tabasco case study on flood-proof infrastructure?

Answer 5

• Frequent flooding caused severe road erosion.
• Strategic reinforcement of key roads to maintain access during floods.
