| Abstract: | Model pile tests under dynamic and static load in soft soil have been done,and research is accomplished on dynamic bearing capacity, dynamic side resistance,dynamic end resistance and dynamic stiffness of pile, accumulation and amplitude of displacement on top of pile.It is concluded that bearing capacity of pile foundation of high speed railway bridge must be reduced by 10 percent to 30 percent. |

| Keywords: | pile dynamic character model test soft soil axial direction |
