%X The vibration problem of pile with variable sections and finite length under exciting force is studied. The influence of the soil under pile toe and surrounding pile is considered. With Laplace transforms,the analytical solutions on the velocity mobility and the dynamic stiffness at the head of the pile are derived. Based on the solutions,the influences of degree and length as well as location of pile defects on the vibration properties are studied.
