| Abstract: | 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. |
