摘　　要：在同江黑龙江铁路特大桥钢桁梁设计过程中,结合中、俄两国规范对钢梁设计的有关规定、以及设计活载标准进行了对比分析,研究了我国钢桁梁设计的预留活载情况,为同时通行中、俄两国列车的钢桁梁设计提供了理论依据,同时,为类似的国际铁路桥梁设计提供参考。In the design process of Tongjiang-Heilongjiang River Railway Bridge,the relevant requirements of steel truss girder specified in both Chinese code and Russian code were considered comprehensively,and the live loads were analyzed comparatively,also the situation of reserved live loads in steel girder design in China were studied.This study can provide the theoretical basis for the design of the steel truss girder bridge which Chinese trains and Russian trains will run on the same bridge,and can serve as a good guidance for the design of other international railway bridges in future.

关 键 词：国际铁路 套轨 钢桁梁桥 预留活载发展系数
