Evaluation of Track Geometry on a Long Span Steel Trussed Cable-Stayed Bridge
In order to investigate the track geometry on a long span steel trussed cable-stayed bridge, in this paper, a plane model is built include suspension cable, pylons, floating system and so on based on FEM to calculate the track geometry under temperature load, wind load and train load. Then evaluate the track geometry from the aspects of line profile and track static geometry size deviation. The result shows that the track geometry indicators like vertical curve radius, gradients and static geometric deviation under temperature load and wind load are better than the indicators under train load. The maximum values of track geometry indicators are all appeared in the bridge piers, mainly because the support stiffness is great different between in the bridge pier and in the mid-span cross-section. It is suggested that the flexibility of piers should be appropriate increased to reduce the support stiffness mutation.
