THE DESIGN AND CONSTRUCTION OF MEDWAY VIADUCT
Construction of a major viaduct over the River Medway for the Channel Tunnel Rail Link (CTRL) has recently been completed. The first stage of this new high-speed line is due to open in 2003. The viaduct crosses over the Medway River upstream of the town of Rochester. This paper describes the design and construction of the bridge to meet the stringent CTRL railway requirements including passenger comfort. It also describes some of the unique features of the structure design to accommodate rail movements. The viaduct is a multi-span structure 1.2km long with typical approach spans of 40.5m and a central navigation span of 152m. The design was carried out on the basis of the central span being built by balanced cantilever techniques and the side spans being incrementally launched from the abutments. The structure was designed using bonded prestressing for launching and cantilevering together with external prestressing for continuity. The paper examines some of the particular design aspects of the structure including the trackwork furniture, articulation, movement joints and some of the construction methods used.
