| 摘 要： | 针对水平地震作用下的桩土相互作用体系,利用有限元软件ANSYS建立了单桩-地基土系统三维有限元模型。运用此模型,对系统进行考虑地基土的材料非线性和桩土界面状态非线性的单桩横向地震响应计算,并进行了自由场响应的计算。计算结果表明:土体的材料非线性与桩土界面状态的非线性特性对单桩的横向水平地震响应有着一定的影响。

| Abstract: | Considering the pile-soil interaction system under the horizontal seismic loads,this paper use FEM software ANSYS,sets up the FEM model of single pile-foundation,use this model on the condition of soil's material nonlinear and simulate pile-soil's interface bonding or separation,calculate the lateral seismic response of single pile.Also,we calculate the response of free field.The result indicates the material nonlinear characteristic of the soil body and the pile-soil's state nonlinear influence to the single pile's seismic response. |
