Global stability studies using slip circle analyses are routinely performed for retaining walls constructed along sloped embankments. Consolidated-Drained Direct Shear Tests and Consolidated-Undrained Triaxial Tests with pore pressure measurements are used to model long term performance of these walls. For walls constructed along flat grades, simple bearing capacity studies are usually adequate.

There are five (5) factors that can lead to excessive wall creep that are not identified by the conventional studies indicated above. This paper identifies these factors and addresses simple measures that can be implemented to improve long term wall performance and minimize wall creep.
