    摘要
  • 摘要: 目前，在城市地铁隧道施工中常常遇到邻近市政管线的影响。而较多的研究集中在隧道施工引起的周围地层变形上，考虑邻近管线 作用的隧道开挖理论分析方法并不多见。为此，针对隧道洞周引入椭圆化非等量径向土体位移控制模式，将邻近管线视为 Euler-Bernoulli 梁，同时将层状地基土体视为弹性层状地基模型，提出了 层状地基中隧道开挖引起邻近管道纵向变形的 DCBEM-FEM （位移控制边界元与有限元） 耦合分析方法。最后结合现场实测数据和位移控制有限元数值模拟进行分析，验证了本文方法的有效性。研究表明： DCBEM-FEM 耦合 方法可以较好的体现隧道开挖所引起的地层损失问题，同时本文方法在考虑邻近管线作用时具有较好的计算精度。研究成果可为合理制定城市地铁隧道施工对邻近管线的保护措施提供一定的理论依据。
    Abstract: The response analysis of subway tunneling on adjacent municipal pipelines is an important problem that geotechnical engineers may need to face when designing new tunnels. However, previous researches usually focus on the ground movements induced by tunneling. Few investigations into the problem of tunneling in layered soils are available considering the effects of adjacent pipelines. The oval-shaped non-uniform convergence deformation controlled model is imposed to the tunnel opening boundary. The adjacent pipelines are regarded as the Euler-Bernoulli beams. The surrounding soils are regarded as the elastic layered soil model. The DCBEM-FEM (Displacement controlled boundary element method -finite element method) coupling method is presented for response analysis of tunneling on adjacent pipelines in layered soils . Finally the accuracy of the proposed method is demonstrated by means of the observed data and the displacement controlled finite element numerical method. The results indicate that the ground loss due to tunneling can be reflected in the DCBEM-FEM coupling method. T he computed accuracy of the proposed method is better compared with other data . It may provide a certain basis to draw up correctly protective measurements for adjacent pipelines influenced by adjacent tunneling.
