Best Practices for Zero Retaining Wall Failures - Increasing Global Stability Options


If your retaining wall has global stability concerns, there are several things you can try to improve the stability:
  • Increasing the length of the geogrid layers to force the minimum slip arcs deeper into the hillside.
  • Increasing the depth of buried block to force the minimum slip arcs deeper into the hillside.
  • Increasing the strength of the geosynthetic reinforcement layers to force the minimum slip arcs deeper into the hillside.
  • Increasing the friction angle of the infill soil will increase the soil’s shear resistance which will increase stability. (ref. BP, Chapter 9.3)

Allan Block is working to achieve our industry initiative of Zero Wall Failures. With our Best Practices Manual and experience in the industry we are trying to expand the knowledge base for the design of segmental retaining walls (SRW's) by communicating and educating the professionals in the industry.  To see the full Best Practices Manual, visit allanblock.com to download today and keep an eye out for more industry Best Practice recommendations here.
