| 摘 要： | 采用三维非线性有限元法进行单桩的工作性能分析，在桩土之间引入Goodman接触面单元，建立有限元-接触面单元相耦合的非线性数值模型。利用大型有限元分析软件ANSYS对竖向荷载作用下的单桩与土相互作用进行计算分析。结果表明，计算分析与实测基本吻合，表明采用的耦合方法能对桩的受力变形特性进行较好的模拟。

| Abstract: | In this paper, the 3D-nonlinear-finite-element method was employed to analyze the interaction of a pile-soil system, The Goodman interface elements were defined to contribute a nonlinear numerical model for the coupling finite elements and interface elements. The interaction of a pile-soil system was analyzed by using ANASYS, Case studies showed the results are fairly well consistent with the field observations. So then the coupled analytical method in this paper could be a solution to analyze the bearing and deforming behaviors of single pile under vertical load. |
