👉Factors affecting soil compaction during soil improvement
💫The main factors are:
- Moisture Content → At optimum moisture content (OMC), maximum dry density is achieved. Too dry or too wet reduces compaction.
- Soil Type → Clay, silt, sand, and gravel compact differently. Coarse-grained soils are easier to compact.
- Compaction Effort → Type of compaction equipment (roller, rammer, vibrator) and number of passes increase density.
- Layer Thickness (Lift thickness) → Thin layers compact better than thick ones.
- Grain Size Distribution → Well-graded soils compact better than uniformly graded ones.
📜Factors causing slope instability and leading to failure
- Gravitational force (self-weight of soil)
- External loads (buildings, traffic, surcharge)
- Water infiltration & pore water pressure rise
- Erosion at the slope toe
- Earthquake or vibration loading
- Weak foundation soil / slip plane formation
- Weathering & vegetation removal
