摘　　要：利用桥梁有限元分析软件建立桥梁承载能力验算模型,对兰青线DK81+796(24+32)m简支T梁在超重火车过桥时进行承载能力理论分析,评估桥梁结构现有承载能力及其使用条件,为超重货物列车的安全运营提供理论依据和技术建议。The bridges carrying capacity checking model is built by using finite element analysis software for bridges, and the theoretical analysis of carrying capacity of simply supported T beam is made when overweight train is over the bridge in DK81.. 796 （24 ＋ 32） m of Lanzhou -Xining Qinghai Railway, which provides a theoretical basis and technical advice for the safe operation of heavy freight trains.
