盾构隧道下穿对高铁桥梁的影响研究

Research on Influence of Shield Tunneling Underpass on High-Speed Railway Bridges

某地铁区间采用盾构法施工,盾构侧穿高铁桥桩,采用三维数值分析的方法研究盾构施工对高铁桩基的影响,分析桥梁稳定性是否满足要求,提出相应的盾构施工辅助措施,为今后类似工程的开展提供了一定的借鉴。

A metro section is constructed by shield method, and the shield side passes through the high-speed railway bridge pile. The three-dimensional numerical analysis method is used to study the influence of shield construction on the high-speed railway pile foundation,analyze whether the bridge stability meets the requirements, and put forward the corresponding auxiliary measures for shield construction,which provides a certain reference for the development of similar projects in the future.
