【Abstract】 In this paper,the reasonable mechanical model are established to single pile foundation in layer elasto-foundation bed according to Winkler layer elasto -foundation bed soil model in terms of characteristics analysis. By means of dynamic analysis,the analytical solutions for the lateral free vibration characteristics and the forced responses under the action of the lateral dynamic loading and lateral seismic loading of the single pile foundation are given. The analytical formulas described in the paper have provided a new method for the lateral dynamic response analysis of the single pile foundations under the action of the lateral dynamic loading and lateral seismic loading in layer elasto -foundation bed in the paper.更多还原
