Abstract :
Characteristics of the large self-weight and large load of heavy machine tool, lead to the change of ground motion character, its dynamic response is directly affected by pile-soil structure. This paper, through the introduction of large guide joint, the pile soil contact surface, boundary conditions of artificial interception area and the equivalent stiffness and damping, builds an easily achieved soil-pile-heavy machine tool dynamic model, studies the system step response law in the different soil layer, provides the theory basis for the foundation soil design of heavy machine tool.
