| Abstract: | In this paper, a reasonable machanics model is established to End-bearing pile foundation in layer elasto-foundation by means of characteristics analysis, and according'tQ layer elasto-foundation soil model to carry out the dynamic analysis of the End-bearing pile, the analytical solutions for the axial free vibration characteristics and the coercion responses under the action of the vertical seismic loading of the End-bearing pile are given. A new analytical method is furnished to the analytical formulas for the axial dynamic response analysis of the End-bearing pile foundation in layer elasto-foundation in the paper. |
