【摘要】 本文对无限层弹性地基中单桩基础通过特性分析建立了合理的力学模型，按分层弹性地基土模型对桩进行动力分析，给出了桩基础轴向自振特性及在竖向地震载荷与动力载荷作用下强迫反应的解析解，文中的解析公式为无限层弹性地基中的单桩基础轴向地震反应分析提供了一种新的解析方法。更多还原

【Abstract】 In this paper, a mechanical model for single pile in infinice-layer elastic foundation is set up through characteristic analysis;dynamic analysis of pile is made according to layer elastic foundation soil model and the analytic solution for axial free vibration characteristics of pile and forced response to actions from vertical seismic and dynamic loadings is given.And the analytic formula in this paper offers a new analytic method to analyse axial response of single pile in infinite-layer elastic foundation to earthquake.更多还原
