| Abstract: | In this paper,the reasonable mechanics model are established to end-bearing pile foundation in layer elasto-foundation bed according to Winkler layer elasto-foundation bed soil model by means of characteristics analysis. Using dynamic analysis.the analytical solutions for the lateral free vibration characteristics and the coercion responses under the action of the constant axial force and lateral seismic loading of the end-bearing pile foundation are given ,that a new analytical method is furnished. |
