| 摘 要： | 基于Hardin-Drnevich模型，采用非线性有限元得到基础－地基相互作用中基础转角和弯矩之间的关系，建立了单自由度结构－非线性地基相互作用模型。用平均法得到主共振定常解并讨论其稳定性。从分叉图出发讨论了结构－地基相互作用的动力行为，得到了一些有益的结论。

| Abstract: | In the paper, based on Hardin Drnevich model, the nonlinear finite element program is applied to obtain the relationship between moment and rock angle of foundation. The computation model of structure foundation nonlinear interaction system is derived. The method of average is used for obtaining the steady state solution and stability performance of the primary resonance. By discussing bifurcation diagram, the dynamical behaviors of structures foundation interaction system are analyzed. Some regularity conclusions have been drawn through the analyses of numerical examples. |
