Target FOS for static global stability analysis of retaining wall?
All other factors being equal, I'm curious what number you all set as the target threshold for global stability of a retaining wall when using SLIDE or GeoStudio or whatever. I have a number but I don't want to bias the conversation. I know about FERC values for embankment dams which I consider to be gospel for those purposes, but when it comes to the 15ft tall MSE wall at your local multi-family housing project, what number are you designing for, or hoping to see when evaluating the proposed conditions? Thanks. Again this is static analysis for typical conditions, short-term and long-term analysis as appropriate.
