Dashengguan Bridge—The Largest Span Steel Arch Bridge for High-Speed Railway
Abstract:The Nanjing Dashengguan Bridge is a key project on the Beijing–Shanghai high-speed railway; it is designed to handle a speed of 300 km/h. The main bridge has a large-span continuous steel arch truss structure with a total length of 1615 m. The two main spans over the main navigation channels of the Yangtze River are steel arch trusses, each of which is 336 m long. The arches comprise three truss planes above the orthotropic deck. Erection of the steel arch truss adopted the double cantilever method with auxiliary cables supported by towers on piers.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
SEI is printed in Switzerland; ISSN 1016-8664; E-ISSN 1683-0350
