Retaining Wall Analysis 🧱

Analyse the stability of a retaining wall.

In accordance with Eurocode 7. Only considers long term drained conditions & water at ground level. This prediction is in accordance with the Net Available passive resistance method developed by Burland, Potts & Walsh.
Your Retaining Wall Profile
1. Modify the soil parameters
2. Control retaining wall profile
Use this menu to update the retaining wall profile.
Depth to top of base m
Depth > 7m not recommended. Check that base is within soil and above toe.
Base thickness m
Max thickness of 3m & check that soil is deep enough.
Base offset (inside) m
Max offset of 5m & min of wall thickness/2.
Base offset (outside) m
Max thickness of 5m & min of wall thickness/2.
Wall thickness m
Max thickness of 3m.
Surcharge kPa
Enter a number between 0 and 150.
