Internal Design Of Mechanically Stabilized Earth (Mse) Retaining Walls Using Crimped Bars, Bernardo A. Castellanos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current design codes of Mechanically Stabilized Earth (MSE) Walls allow the use lower lateral earth pressure coefficient (K value) for designing geosynthetics walls than those used to design steel walls. The reason of this is because geosynthetics walls are less rigid permitting the wall to deform enough to work under active pressures instead of at rest pressures as in steel walls.

A new concept of crimped steel bars was recently introduced. This new type of bar was tested for tension and pullout behavior. Results on tests made on crimped bars show that putting those crimps in the steel bar will …

Development Of Mechanically Stabilized Earth (Mse) Wall Inspection Procedure For Failure Mode Analysis And Risk Assessment, Ryan Bruce Maw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A large component of the State of Utah's transportation network involves the use of MSE walls, which have proven useful in infrastructure for their reduced costs and footprint compared to other alternatives. As effective as MSE walls have been in responding to demands in transportation, they also have inherent challenges. For the majority of MSE walls the structure is limited in observation as structural components are buried as part of the soils mass. This inability to observe at can lead to the development of complex failure mechanisms, which can be difficult to assess and anticipate. As society becomes increasingly reliant …
