| Abstract: | The vibration problem of finite length pile with viscoelastic properties under vertical exciting force is developed, the influence of the bottom and the surrounding soil is taken account of. With Laplace transforms, we draw out the pile's impulse response function, and the formula of velocity under semi sine wave exciting. Based on the solution, the influence of pile's viscous damping on the vibration properties of pile soil system is studied. |
