摘要：

Considering the interaction between visco-elastic soils and a variable section impedance pile with arbitrary bottom boundaries,the dynamic response at the pile head to a arbitrary dynamic torque is theoretically investigated. By Laplace transforms and the transmit property of impedance function, the analytical expression of the impedance function and solutions of the displacement and velocity response function in frequency domain and in time domain at the pile head are derived. The characteristic of interaction between soil layers is also theoretically investigated here.
