Assumptions of Coulomb's Earth Pressure Theory
Coulomb's Earth Pressure Theory provides a framework for understanding how soil exerts pressure on retaining walls. The theory is based on several key assumptions:
1. Friction Between Wall and Backfill
- Inclusion of Friction: The theory acknowledges that friction between the retaining wall and the backfill material affects the overall pressure distribution.
- Influence on Stability: This frictional force plays a critical role in the stability of the wall and can reduce the lateral earth pressure.
2. Failure Plane Assumption
- Planar Failure Surface: Coulomb assumes that the failure surface develops in a planar fashion, which simplifies the analysis.
- Importance of Geometry: This assumption helps in establishing how the soil mass will move or fail under stress.
3. Cohesionless and Dry Soil
- Soil Characteristics: The theory is predicated on the assumption that the backfill soil is cohesionless and dry, focusing solely on the effects of gravity.
- Simplification: By excluding cohesion, the analysis becomes more straightforward, allowing for a better understanding of lateral pressure.
4. Vertical Wall Face
- Vertical Wall Assumption: It is assumed that the face of the wall in contact with the backfill is vertical.
- Effects on Pressure Distribution: This assumption is critical as it directly impacts how lateral earth pressures are calculated.
In summary, all options (A, B, C, D) accurately represent the assumptions of Coulomb's Earth Pressure Theory, making them crucial for understanding the behavior of retaining structures.
