Thus the resistance factor and vibration modes of the soil layer are obtained and used to analysis the pile response. by considering the interaction between the soil layer and the pile with boundary condition of continuity of displacement and equilibrium of force at the interface of soil layer and pile, the dynamic equilibrium equation of pile is solved and an analytical solution for the pile response in frequency domain is yielded, which is used to define complex stiffness and mobility at the level of the pile head. based on the convolution theorem and inverse fourier transform, a semi - analytical solution of velocity response in time - domain subjected to a semi - sine exciting force is given
首先通過引入勢函數方法對土體位移進行分解，從而將土體動力平衡方程解耦，求解得到了土層的振動模態和阻抗因子，然後利用該解以小應變條件下樁土接觸面上力平衡和位移連續條件來考慮樁土耦合作用，求解樁的動力平衡方程，得到了樁頂的頻域響應解析解、復剛度和速度導納，利用卷積定理和傅里葉逆變換，求得了半正弦脈沖激振力作用下樁頂速度時域響應半解析解。
