DESIGN OF RETAINING WALL
A retaining wall is a structure designed to resist the lateral pressure of soil when there is a desired change in ground elevation. The wall prevents soil from sliding or eroding away and ensures stability for structures and surfaces.
1. Earth Pressure Calculation
- Use Rankine theory
- Consider:
- Backfill type (dry, moist, submerged)
- Surcharge loads
- Angle of internal friction (ϕ)
- Wall inclination
2. Stability Checks
- Overturning
- Sliding
- Bearing pressure
- Global stability (if required)
3. Structural Design
- Design for bending moment, shear force, and reinforcement
- Use limit state method as per IS 456:2000
- Check serviceability limit states
