| 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. |
