3D numerical analysis and evaluation of the influence of tunneling on frame buildings

  • 摘要: 城市地铁建设需要针对隧道开挖对地面房屋的影响进行合理的评估。采用能够考虑土体小应变刚度特征的本构模型,通过三维数值模拟以计算典型工况下隧道开挖引起的地面不同位置框架结构房屋变形,进而分别采用Burland方法及改进的Boone方法对房屋所受的影响进行评估,并将两种方法的评估结果进行对比。结果表明,采用Burland方法可能会低估框架结构房屋所受的影响,从而导致预测结果偏于不安全。同时,采用改进的Boone方法的预测结果表明,框架结构房屋的损坏很可能出现在地表沉降曲线反弯点附近的位置。
    Abstract: Buildings on the ground surface are inevitably influenced by tunneling. This paper presents the results of a 3-D numerical analysis on the deformation of a frame structure induced by tunneling using small-strain stiffness model for soils. The numerical results are compared with those predicted by the Burland method and the modified Boone method. The comparison demonstrates that the predicted results of Burland method are not reliable in some cases, and may seriously underestimate the deformation of frame buildings.
