| 摘 要： | 浅埋隧道穿越上部桩基础的问题值得关注。在概述目前研究成果的基础上，采取两阶段分析方案，利用分层土体的剪切位移法，着重分析了浅埋隧道开挖引起的土体移动对隧道顶桩位移及轴力的影响，并与整体有限元计算结果进行了比较，结果表明该计算方法是合理的，且计算量小，无需建立复杂的计算模型，在工程领域有较好的实用性。

| Abstract: | More attention has focused on the issue of shallow tunneling across pile foundation.In this paper,a two-stage approach is used to analyze axial forces and displacements of pile caused by shallow tunneling.Free-field tunneling-induced ground moving is estimated based on an analytical solution given by Loganathan and Poulos(1998a).A simplified finite difference formulation is then developed,based on the Winkler model of soil reaction,for computing the pile response induced by the estimated free-field ground movements.Finally,a case history has been studied with both the proposed two-stage approach and a complete finite element analysis.The results obtained by both methods are in fair agreement.Because the simplified method does not need complex model,it can be used well in engineering. |
