摘　　要：桥头跳车问题影响着铁路建设和运营,迫切需要解决。结合胶新铁路当地实际情况,开展相关研究,有效减轻差异沉降和桥头跳车的影响,具有重要的现实意义。首先介绍了胶新铁路试验段的基本情况以及试验采用的仪器和测试原理,然后详细分析了不同地段通车前和通车后路桥过渡段的沉降变形特征。The problem of bumping at bridge head affects railway constriction and operation, which need to be solved urgently. Combined with the local practice of Jiaozhou-Xinyi Railway, related research is conducted to effectively reduce the influence of differential settlement and bumping, which has important practical significance. This paper first introduced the basic situation of Jiaozhou-Xinyi Railway test section and the instrumentation and principle for test; then analyzed the settlement characteristics of road-bridge transition section in different sections before and after opening to traffic.
