| 摘 要： | 本文研究水平地震作用下桩-土体系中桩基的地震反应,为桩基的抗震设计提供依据。以单桩为研究对象,建立有限元分析模型并加以验证,再根据场地条件选取输入波,分析了桩、桩-均匀土体、桩-分层土体3种模型处于弹性和弹塑性状态下的桩基的变形特性和受力性能。研究表明,桩动力分析时必须考虑桩周土的影响,若按静力法的桩-弹簧模型进行桩的设计会使桩身不安全。

| Abstract: | The deformation and the internal force of a pile are affected by the pile-soil interaction.The single pile is taken as a research object and the finite element method is used.Firstly the analytical model is verified,then the input ground motion is selected according to the site condition,and the deformation and the internal force of a pile in the model of pile,pile-soil,pile-layered soil under the condition of elastic and elastic-plastic are researched. |

| Keywords: | pile dynamic interaction soil-structure interaction elastio-plastic analysis seismic |
