| Abstract: | According to existing calculation theories, actual experimentation data are analyzed synthetically. Based on the inter-action principle and calculating model of beam and rail, the distributing rule and effect mechanism of the expansion and contraction forces of welded rails are analyzed when continuously welded rail is laid on continuous railway beam bridge. |

| Keywords: | continuously welded rails expansion and contraction forces continuously beam bridge |
