| Abstract: |
| The torsional oscillations of single pile embedded in layered foundation are investigated by means of integral transformation and Muki’s methods. In the analysis, the Hankel transformation is made on the governing equations firstly and the primary parameter solutions and stiffness matrix of single layered foundation are established. The recurrence matrix of layered foundation is obtained. Then, using the recurrence matrix, boundary condition and deformation compatibility conditions, the fundamental integral equation of the torsional oscillation of single pile embedded in layered foundations is established and programmed. At the end of the paper, the torsional responses of the rigid single pile in degenerated layered foundation are obtained and show good agreement with the existing theoretical solutions. Furthermore, the dynamic torsional responses of single pile in two layered foundation are analyzed by numerical examples and the influence of pile-soil parameters on the dynamic response is investigated. The conclusions obtained have some guidelines on practical engineering and torsional wave testing of pile foundation. |
