Methods to Improve Bearing Capacity of
Soil
1. Compaction: Densifying soil by rolling, ramming, or vibration increasesits strength and reduces settlement.
2. Drainage Improvement: Removing excess water from soil enhanceseffective stress and bearing capacity.
3. Confining Pressure: Lateral confinement with sheet piles or retainingwalls increases soil resistance.
4. Grouting: Injection of cement or chemical grouts into soil voids improvescohesion and density.
5. Reinforcement: Using geotextiles, geogrids, or stone columnsstrengthens soil structure.
6. Soil Replacement: Replacing weak soil with stronger granular materialbeneath foundation.
7. Vibro-flotation: Technique used for deep densification of granular soils.
8. Preloading: Applying temporary load to compress soil before actualconstruction.
