In order to study the interaction between high-speed railway bridge and track on the frame pier, the beam-rail-frame pier-pile foundation finite element model of the high-speed railway bridge was established by both using the beam element with rigid arms to simulate the bridge and using the nonlinear spring to simulate longitudinal resistance of the line. Taking a (3×32) m simply-supported beam of the frame pier using steel-concrete combination on the Hefei-Fuzhou line as a case, the transfer rule of CWR (continuously welded rail) longitudinal force on the frame pier was analysed, and it was discussed that the design parameters of the longitudinal resistance model, live load model, beam-column joint stiffness, stiffness of pile foundation, temperature increase range, wind pressure and so on made the impact on the longitudinal force. They will be of reference value to the design of the high-speed railway frame pier in the future. |
