水平动力荷载下单桩动力分析模型研究

Research on single pile dynamic analysis model under horizontal dynamic load

针对在强烈的地震运动过程中,桩周土将产生较大的非线性应力和位移,桩基的动力响应呈现非线性的情况,在Winkler地基梁模型的基础上,引入描述迟滞非线性系统本构关系的Bouc-Wen经典模型,介绍了单桩非线性动力响应的简化分析模型及模型相关参数的假定,以使计算过程得到简化。

In view of strong earthquake motion process, the pile soil would produce larger non-linear stress and displacement, the dynamic response of pile foundation was non-linear, on the basis of Winkler foundation beam model, this paper introduced the Bouc-Wen classic model described the hysteresis non-linear systems constitutive relation, introduced the simplified analysis model of single pile non-linear dynamic response and the assumptions of model relevant parameters, in order to make the calculation process simplified.
