Multi-Segment Pile-Supported Bridge Approach Slabs For Control Of Differential Settlement, Ahmed Bahumdain
Multi-Segment Pile-Supported Bridge Approach Slabs For Control Of Differential Settlement, Ahmed Bahumdain
Theses and Dissertations
The roughness of the transition between the bridge and the roadway is a well-known issue that affects roughly 25% of the bridges in the United States. As soil underneath the approach slab settles, deferential settlement develops between the bridge and the approaching roadway. This may negatively affect the ride quality for travelers and result in substantial long-term maintenance costs. Because of the differential settlement, bumps could develop at the ends of the bridge when abrupt changes in slope (exceeding 1/125) occurs.
This study was aimed at mitigating the formation of bumps at the ends of the bridge through a new …

ABSTRACT
The long-term maintenance problems associated with expansion joints, which are used to accommodate bridge movements in conventional bridges, have been the primary motivation for the use of integral abutment (jointless) bridges. These bridges rely on the interaction between the structure and the surrounding soil to accommodate bridge movements without the use of any expansion joints on the bridge superstructure. As the bridge superstructure expands and contracts due to seasonal thermal and other strains, relatively large forces can develop in the pile near the pile-cap interface. These reversible moment and shear forces can lead to localized damage near the top …
