摘　　要：随着列车速度的提高 ,上承式钢板梁横向振幅过大的问题日益突出 ,它直接威胁行车安全。提出用粘弹性阻尼器控制上承式钢板梁的横向振动 ,并在京广上行线羊楼司桥上进行现场试验。结果表明 ,粘弹性阻尼器能有效地减小上承式钢板梁的横向振幅 ,为进一步选择合适的粘弹性材料提供了试验依据。As the raising of train speed,the proplem of larger transverse vibration amplitude of deck steel plate girder is outstanding increasingly,which threatens the safe of train directly The transverse vibration control for deck steel plate girder using viscoelastic damper was presented and tested on Yanglousi Bridge in Beijing Guangzhou up track The test results proved that the viscoelastic damper can decrease the transverse vibration amplitude of deck steel plate girder effectively,and provided test basis for electing the suitable viscoelastic materials
