Survey, Evaluation, and Long-Term Monitoring of the EDC GRS Abutment Performance for Multiple-Span CDOT Bridges Replacement Project
| 项目名称： | Survey, Evaluation, and Long-Term Monitoring of the EDC GRS Abutment Performance for Multiple-Span CDOT Bridges Replacement Project |
| 摘要： | The Colorado Department of Transportation's (CDOT's) project to replace the twin bridges over the Union Pacific Railroad and Smith Road incorporates innovations that implement the Colorado Department of Transportation/Federal Highway Administration (CDOT/FHWA) mandate - EDC GRS (Geosynthetic Reinforced Soil) abutment technology. These twin bridges carry I-70 eastbound and westbound traffic on three-span horizontally curved steel welded-plate girder structures. The mid-span piers are founded on deep foundation; however, the GRS abutments are supported by spread footings and founded on embankments. This unique feature of a GRS transition zone, to a GRS abutment founded on an embankment (shallow foundation), to pier (deep foundation) is a new design methodology for eliminating bridge bumps. The objective of this study is to validate the performance of GRS abutment for multi-span bridges and the use of geofabric without positive connections to the fascia blocks for GRS retaining walls. |
