| 摘要： | One of the newest entrants into the bridge-building field is the Channel Bridge. The Channel Bridge is a patented, precast-concrete superstructure system that uses posttensioned segmental construction. The Channel Bridge is appropriate when a replacement or new alignment structure requires an increase in the vertical underclearance. The system was developed in 1990 for the French Highway Administration, and 11 Channel Bridges have been built in France. In the United States, the Highway Innovation Technology Evaluation Center (HITEC) is conducting a two-phase evaluation of the Channel Bridge. Phase I is a technical design analysis phase and was completed and documented in a HITEC reported entitled "Evaluation Findings: The Segmental Concrete Channel Bridge System," dated March 1996. The performance history focused on the Channel Bridges in France, while the design evaluation focused on specific design issues related to segmental bridge construction in general and to the unique aspects of the Channel Bridge system. Phase II is a demonstration phase and is currently underway. The report will include the evaluation of two beams and winches. The New York State Department of Transportation is replacing two state bridges with the Channel Bridge system: Carpenter Road over Metropolitan Transportation Authority Metro North Railroad in East Fishkill in Dutchess County and state Route 17M over state Route 17 in Wallkill in Orange County. The results of this demonstration will also be published in HITEC's Phase II Evaluation Report. |
