Mechanically Stabilized Earth Wall Abutments for Bridge Support; Final rept

摘要

The research study starts with a review, based on published literature and other accessible sources, of current design methods and construction practices in North America and other parts of the world where MSE bridge abutments have been constructed. The synthesis of this information is then used to perform preliminary designs in case examples of interest to INDOT. These examples are classified in terms of bridge geometry, loading, and foundation soil conditions. Results are obtained in terms of ultimate limit states. i.e. the external and internal stability of the MSE wall, according to AASHTOs and FHWAs guidelines. The ultimate goal of the research is to formulate recommendations that will result in more effective design and improved economy of highway bridge abutments by using MSE technology whenever it is the best solution. It is expected that the results of the study will contribute to new or improvement INDOTs guidelines and specifications in this particular area.
