【摘要】 通过对铁路钢梁桥的实测数据分析 ,采用车桥动力相互作用的计算模型 ,计算了提速后的铁路钢桥的横向振动 ,理论计算结果与实测数据基本吻合。提出了采用货车脱轨安全度来确定铁路钢梁桥的横向振幅允许值更多还原

【Abstract】 Based on analysing the testing data of the railway steel bridges,by adopting the vehicle bridge reaction model, the lateral dynamic responses of the railway steel bridges are studied. The allowable lateral amplitudes based on the derailment factor of the freight vehicles are suggested.更多还原
