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
