2a. what are the effect of compaction on civil engineering project?
Expert Solution
Step 1
COMPACTION- Soil compaction is the process in which stress applied to a soil causes densification as air is displaced from the pores between the soil grains.
Purpose of compaction - Compaction of the soil and removing air voids generally increases the soil’s sheer strength, decreases its compressibility, and decreases its permeability. It will reduce the voids ratio making it more difficult for water to flow through soil.
We conclude that there are several objectives to soil compaction:
• Increase bearing capacity
• Increase durability
• Increase resistance to deformation
• Decrease frost damage
• Increase stability
• Decrease permeability
