According to characteristics of force and displacement of welded turnout on bridge, the turnout-bridge-platform integration computation model was established; the model was solved by finite element method. Taking the Meichi No.1bridge on Zhejiang-Jiangxi railway line as the example, the force and the displacement characteristics of the welded turnout on bridge were analyzed. The temperature force and the displacement of welded turnout on bridge was measured, the site test proves that the calculated results are consistent with the measurements. The analysis and the test prove that the turnout -bridge-platform integration computation model to solve the longitudinal force and displacement of welded turnout on bridge was feasible; the forces and displacements of welded turnout on bridge and CWR on bridge were different, Some parameters Influencing the longitudinal force and displacement of the welded turnout on bridge should be calculated, such as the temperature of rail, the disposal of turnout, the location of turnout and bridge, and so on; in dense turnout area, such as throat zone, the interaction between turnouts was considerable, for the sake of calculating the force and displacement of turnout on the bridge well, the integration computation model including all the turnouts and bridges should be established.
