摘要：
In order to, test the dynamic performance of long-span steel box-section arch bridge, the experimental study on the dynamic Performance of the 140m steel box-section tied arch bridge over the Ting Si River Bridge in the Wuhan-Guangzhou Passenger Dedicated Line is carried out. When the CRH2 EMU runs across the steel box-section arch bridge in different speeds, the tested results of the bridge dynamic responses show that the lateral and vertical stiffness are larger, the vertical and lateral natural frequencies and the other dynamic performances of the bridge can meet the requirements of the relevant norms. The bridge structure can meet the security requirements when CRH2 EMU runs on it in the speed of 250 to 350km/h.
