Research methods: The integrated method of economic and technical analysis is adopted based on the features and experience of design of railroad-overpass bridge.
Research results: In view of taking construction method and making structural design of railroad-overpass bridge appropriately to guarantee the safe operation of the railway, the appropriate common schemes of overpass bridge available for railway section and terminal are presented.
Research conclusions: For the bridge in railway section，it is adapted to use box beam，T beam and hollow slab beam and constructed by adopting precast erection method. For the bridge in railroad terminal，it is adapted to use cable- stayed bridge，large-span rigid frame bridge or composite steel and concrete beam bridge and constructed by adopting erection methods of swing，cantilever and jack-in.
