Understanding the Retaining Wall and Active Thrust
When dealing with a retaining wall that supports an inclined backfill of cohesionless soil, it is essential to analyze the behavior of lateral earth pressures. The active lateral thrust, denoted as Pa, is a crucial element in this analysis.
Active Lateral Thrust (Pa)
- The active lateral thrust, Pa, is generated due to the weight of the backfill soil and its inclination at an angle β.
- This thrust acts to push the wall outward and is influenced by the soil's angle of internal friction.
Point of Application
- The point of application of the active thrust is a key aspect of retaining wall design.
- For inclined backfill, the resultant active thrust typically acts at a height of H/3 from the base of the wall. This is derived from the geometry of the pressure distribution.
Direction of the Thrust
- The direction of the active thrust, Pa, acts at an angle β with the horizontal.
- This angle corresponds to the inclination of the backfill and is critical in determining the overall stability of the wall.
Conclusion
Based on the analysis of the active thrust on a retaining wall with a smooth vertical face supporting an inclined backfill, the correct statement is:
- Pa acts at a height H/3 from the base of the wall and at an angle β with the horizontal.
This understanding is fundamental for ensuring the stability and design of retaining structures in civil engineering.
