Analysis of the Impact of the Construction of a New Swivel T-shaped Bridge on the Safety of Existing Railway Roadbeds
The 2x56mT structure of the Lunan high-speed railway bridge is built on the Beijing-Shanghai high-speed railway foundation.In order to accurately analyze the safety impact of the new Lurun High-Speed Railway bridges on the existing Beijing-Shanghai High-Speed Railway foundation,a finite element model was established using Midas GTS for safety evaluation.The results show that the deformation effects of the new T-shaped bridge on the existing railway foundation and the impact on the track smoothness caused by foundation deformation both meet the regulatory requirements.
