| Abstract: | In this paper, the reasonable mechanics model is established to pile foundation according to Winkler layer elasto-foundation soil model by means of chacateristic analysis, and dynamic analysis, the analytical solutions for the lateral free vibration characteristic and the coercion response under the action of the constant axial force and lateral seismic loading. A new analytical method is furnished to the analytical formulae for the lateral dynamic response analysis of the single pile foundation in the paper. |
