摘要

    摘要
  • 摘要: 钱江隧道位于钱塘河口，因其特殊地理位置面临涌潮冲击作用。涌潮产生动载，对河床形成冲击将引起隧道结构振动。目前对此振动影响评价尚不明晰，因而有必要进行深入研究涌潮作用下隧道结构动力响应，尤其是隧道纵向振动特性。依托钱江隧道工程，针对涌潮荷载作用下的钱江隧道进行了室内模型试验，用激振器产生的激振力模拟涌潮产生的动荷载，用加速度计测试隧道的动力响应。最后，通过与动力有限元程序计算结果进行对比，探讨了影响隧道动力响应的规律。
    Abstract: The tidal bore in Qiantang River leads to sharp rise of water level and powerful impact on the riverbed, which will cause the tunnel vibration. However, it is not able to predict the vibration of tunnels under tidal bore clearly now. Consequently, it’s necessary to conduct feasible researches on the dynamic response of the tunnels, especially the characteristics of the longitudinal dynamic response. Model tests on dynamic responses of a small tunnel instrumented with miniature accelerometers are performed. Vibratory loadings are produced on the soil surface by an electric exciter to simulate dynamic loading from tidal bore. The test results are compared with those from a simplified method to investigate the dynamic responses of the tunnel. The factors that affect the dynamic response of the tunnel are explored.
