Abstract：Research purposes:With gradual popularization of the European norms in the world，the European structural standards in particular in the norms have progressively shown characteristics as international general standards. Although the Chinese railway has set up its own system of specifications，however, to further develop and popularize its specifications in both China and the world，Chinese railway needs to follow the modern international scientific achievements and familiarize itself with the characteristics of the system of the European norms and master them for application.
Research conclusions:From the research on the choice of the European bridge specifications，the author reveals the following findings:(1)The new version of the European specifications，which resulted partially from deletion and combination of relevant contents of the old version and was edited with layout according to professional codes，has optimized systematization and methodization of the system.(2)Values range and calculation methods have been stipulated for various parameters on train load，derailment load，traction-braking load，wind load，etc. for railway bridge design according to the new specifications system.(3)The ultimate-limit design based on complete probability is adopted for the European specifications. Being different from the Chinese specifications，its anti-seismic design is arranged in two stages for seismic fortification with an effective checking-calculation method，i. e. linear analysis and time-lapse technique.(4)The above-stated choice of various parameters for railway bridge design under the new specifications system and the main differences on bridge design between the European and the Chinese specifications may provide valuable reference to the Chinese engineers who intend to adopt the European specifications for bridge design.
