Compaction Methods for Cohesionless Soils:
1. Vibration technique
2. Flooding the soil
3. Heavy weights dropped from a height
Explanation:
Cohesionless soils, also called granular soils, are soils that have low or no clay content and do not stick together. These soils are typically composed of sand, gravel, or a mixture of both. Compaction of cohesionless soils is achieved by densifying the soil particles and reducing the air voids. The following compaction methods are suitable for cohesionless soils:
1. Vibration technique: This method involves using a vibrating plate or roller to compact the soil. The vibrations cause the soil particles to settle and pack together, reducing the air voids. This method is effective for loose, granular soils that are difficult to compact using other methods.
2. Flooding the soil: This method involves saturating the soil with water to the point where the water table is just below the surface. The weight of the water helps to compact the soil particles, reducing the air voids. This method is effective for loose, granular soils that are difficult to compact using other methods.
3. Heavy weights dropped from a height: This method involves dropping heavy weights repeatedly onto the soil to compact it. The weight of the weights causes the soil particles to settle and pack together, reducing the air voids. This method is effective for loose, granular soils that are difficult to compact using other methods.
Therefore, options 1, 2, and 5 are suitable for compaction of cohesionless soils. Hence option C is the correct answer.
