Description of the research topic:
The SZE geotechnical research group has focused recently on the performance of bridge abutments as part of integral bridge design. An additional area requiring research is how these abutments perform when subjected to higher than typical river flows. Such flow patterns may occur during flood events or due to other morphologic changes to the river channel or shorline.
Research on abutment scour has generally resulted in empirical relations and design suggestions to reduce the possibility of adverse effects. This research is focused on the interaction of dynamic fluid flow, structural characteristics of the abutment/foundation systems and behavior of underlying soil (or armor material, if used).
The research will take a two-step approach to understanding the problem and its effects.
(1). Study the interaction of fluid/structure/soil/armor to determine the likelihood and extent of scouring conditions and material removal rates.
(2). Applying the predicted removal rates to a soil-structurel interaction analysis to evaluate the effects of scour on the abutment and bridge structure.
Fluid structure interaction would require a Computational Fluid Dynamics analysis approach while the soil structure interaction problem can be modeled with Geotechnical Finite Element Software.
Expected results would lead to a more fundamental understanding of how scour develops, the rate at which it undermines foundations, and the impact it has on strucutural performance of the bridge.
