| Abstract: | In this paper,the reasonable mechanics model are established for single pile foundation in layered elastic ground by means of characteristic analysis,Then the torsional vibration analysis of the pile is carried out according to laycred elasto- foundation soil model,thus the analytic so- lutions for the torsional free vibration characteristics and the coercion rcsponses under the ac- tion of the torsionai seismic loading and torsional vibration loading of the pile are given. The analytic formulas in the paper provide a new analytic methed for the torsional seismic rcsponse analysis of the pile foundation in layered elastic ground. |
