Effect of Wind Load on the Track Structure of Bridge with High Pier and Large Span

Abstract:

The high pier and large-span bridge is high, soft, and have large contact area with the outside world, under the action of wind load, it will occur large vertical and horizontal displacement .This displacement effect on the track structure and will cause rail additional force, lateral displacement and create initial track irregularities, and then reduce the lateral stability of track structure. In this paper, through the large finite element software, we build pier-beam-track model to simulate and analyse the influence on the track structure under the vertical and horizontal wind load, it reached the following conclusion: horizontal wind load basic does not cause rail additional force, but reduce the rail lateral stability; longitudinal wind load can make rail produce certain vertical additional force, but compared to the telescopic additional force, the force basic can be ignored.
