Deformation Control Technology for Pipelines Adjacent to Metro Station with Tunnel-column Construction

  • 摘要: 结合长城桥车站隧道施工对管线的影响,建立隧道支护结构土体地下管线耦合作用的三维有限元分析模型,并对施工过程进行了仿真分析。根据数值模拟结果,提出针对不同材质管线制定的变形控制标准。经现场管线沉降监测数据验证,制定的管线沉降控制标准对现场施工有指导作用。

     

    Abstract: Considering the influence of the Changchengqiao Station tunnel construction on pipelines, a three-dimensional finite element analysis model is established for the tunnel support structure-soil-underground pipeline coupling effect. The whole construction process is simulated and analyzed. Based on the numerical simulation results, deformation control standards for different pipeline materials are formulated accordingly, which are verified by on-site pipeline settlement monitoring data. The established pipeline subsidence control standards play a guiding role for the on-site construction.
