Failure Modes Analysis of UDOT's MSE Wall Inventory

Mechanically Stabilized Earth (MSE) walls have become an important part of the highway infrastructure system. The Utah Department of Transportation (UDOT) has been very aggressive in using MSE walls for many of its projects. Some of the older MSE walls, approaching 30 years of age, are near the end of their design life. This project has three major objectives: 1) Develop a database (inventory) of UDOT's MSE walls, that includes the type of wall structural system, soil conditions, and construction; 2) perform a probabilistic failure modes analysis of UDOT's MSE walls that will identify possible failure modes; and, 3) develop a plan to mitigate the hazards of MSE wall failures to a level of risk that is acceptable to UDOT. The primary outcomes of this project are to be the database (inventory) and a Risk Assessment and Hazard Mitigation Plan against the failure of MSE walls in the UDOT inventory.
