Abstract
The dynamic impedance function of pile in visco-elastic material considering axial loads under lateral dynamic force was analyzed, and the beam dynamic differential equation was used to induce the dynamic impedance function. After analyzing the edge conditions, the dynamic impedance functions were deduced. Contrasted with the result that does not consider axial loads, the axial loads have obvious influence on the dynamic impedance function. And the results show that the dimensionless parameter of the dynamic impedance will change from 6% to 9% when considering axial loads, and dimensionless parameter of the dynamic impedance of the coupling horizontal-sway will increase by 31%.
