Rail-Structure Interaction in Freight and High-Speed Rail Viaducts

摘要

The use of continuous welded rail on long viaducts requires special attention to the interaction between rail andstructure. This paper presents design criteria and analysis approaches to assess rail-structure interaction effectsfor both ballasted track and direct fixation track under heavy and high-speed rail loading. It introduces methods tocontrol such interaction and presents typical results obtained from a parameter study and from a type study for a400-ft span railroad tied arch bridge.
