| Abstract: | According to Winkler's foundation soil model in layered elasto-foundation, a reasonable mechanic model is established to end-bearing foundation piles through characteristics analyses. By dynamic analysis,the analytical solutions for the lateral free vibration features and the coercive responses under action of lateral dynamic and seismic loadings to the end-bearing pile foundation are presented in this paper. The formula given has provided a new analytical method for dynamic response analysis of the end-bearing pile foundations under the action of lateral dynamic and seismic loadings in layered elasto-foundation bed. |
