THE RIGIDITY OF BRIDGES ON HIGH-SPEED RAILWAY LINES

The rigid route elements of a high-speed railway line in the Mittelgebirge region necessitated the construction of a large number of tunnels and bridges. Since the DB had hitherto not used the modern viaduct form with high flexible columns with many spans of the same length, this brought new problems, including those of vehicle movement on such structures. The latter are discussed here. A new feature is the consideration of the overall vehicle/track/bridge system. Study of the problem is assisted by a computer programme developed in the last few years by the DB's Central Office for Operation Management and Data Processing. This was originally used for calculating dynamic stresses in railway bridges, and is described here for the first time. A more detailed examination of the subject is included in a research project of the Federal Ministry of Research which considers irritation for the yard personnel and nuisance for people living in the neighborhood, especially at night, and calls for effective noise abatement measures.
