Failure criteria for Reinforced Earth (RE) Wall /
Mechanically Stabilized Earth (MSE) Walls
A lot of material/guidance (BS/FHWA) is available
regarding the design of RE wall. However very little
has been covered about acceptable failure criteria. By
"acceptable failure criteria", I mean-
- How to quantify the bulging of wall facia at a
particular depth and how much bulge is within
safety limit?
- How severe is outward batter of - let's say 2 degrees
- Should we rectify the bulging/batter or reconstruct
the wall?
- If rectify, then how?
- If rectify by Soil Nailing (which some people have
considered), what is a correct methodology to
estimate the forces in nail and should we completely
neglect the contribution of existing
geosynthetics?
It will be a great help if someone can give reference to
literature which can answer the above questions.

Given the sun exposure for wrap-around facings. Is there a requirement for higher reduction factors for durability? Thanks
