Bearing Capacity Flood- Proof and Frost Proof: Bearing Capacity & Soil Improvement

Question 1

What is bearing capacity?

Answer 1

The ability of soil to support loads applied to it without failure or excessive settlement.

Question 2

What are the main methods to enhance bearing capacity?

Answer 2

1. Compaction – Reduces soil voids and increases density.
2. Adding Sand or Gravel – Replaces weak soil with stronger material.
3. Geogrids and Geotextiles – 4. Provides reinforcement to prevent settlement.
4. Lime Stabilization – Dries out clay and improves stiffness.
5. Cement Stabilization – Increases strength but can cause cracks in clay.
6. Cement with Additives – Enhances soil properties while reducing cracking.

Question 3

How does compaction improve soil strength?

Answer 3

By reducing air voids and increasing effective stress, making soil more resistant to deformation.

Question 4

What is the Optimal Moisture Content (OMC)?

Answer 4

The moisture level at which soil achieves maximum dry density (MPD) during compaction.
