Based on the research background of"affecting factors of dynamic stiffness for stone cutting machine-foundation-pile-foundation system",firstly,this paper analyzes affecting factors of the dynamic stiffness for pile foundation theoretically on the basis of M Novak's research on pile foundation;secondly,the finite element modeling and dynamic simulation analysis of the stone cutting machine-foundation-pile-foundation system are carried out by using ABAQUS software in a engineering case;finally,the factors affecting the dynamic stiffness of the structure are analyzed from the aspects of whether there is pile,soil at the end of the pile,concrete strength of the pile,friction coefficient of the pile and soil,etc.The research results provide certain guidance for the practical application of the project.
