Bearing Capacity Flood- Proof and Frost Proof: Infrastructure on Weak Soils

Question 1

Why is infrastructure on weak soils a challenge?

Answer 1

Weak soils compress and settle under loads, causing structural failure.

Question 2

What are solutions for building on weak soils?

Answer 2

1. Lightweight materials (e.g., EPS, bims, flug sand) to reduce load.
2. Pile foundations to transfer loads to stronger layers.
3. Geogrid-reinforced embankments to distribute stress.

Question 3

What are the advantages of EPS (expanded polystyrene) in road construction?

Answer 3

• Reduces weight on weak soil.
• Prevents excessive settlement.
• Minimizes construction time and cost.
