高速铁路桥墩横向刚度的初步研究

A Study on Lateral Rigidity of Bridge Pier in High Speed Railway

应用车桥耦合振动理论,对高速铁路桥墩的横向刚度进行了初步研究。通过计算和比较不同横向刚度的桥墩时车辆和桥梁的振动响应,指出为了确保高速列车运行的安全和平稳。

Using the theory of coupled vibration between bridge and vehicle, this paper makes an initial study on the lateral rigidity of piers of a medium small span simply supported girder bridge. By calculating and comparing the vibration responses of vehicle and bridge on the piers with different lateral stiffness, it points out that piers should have enough lateral rigidity to ensure the safety and stability for the running of high speed vehicles.
