Dynamic properties of pile in axis-symmetry model are analyzed with MATLAB, and compared with corresponding theory. Influence by distribution of soil-pile shear stiffness is calculated and analyzed. It is indicated that the distribution of soil-pile shear stiffness has little influence on the eigenfrequencies of pile. Therefore it is good to calculate total soil-pile shear stiffness by inverse method with the eigenfrequency of pile. An alternation method is presented to calculate soil-pile press stiffness and soil-pile shear stiffness with the first and second eigenfrequency of pile, so pile capacity can be computed. Pile bearing capacity can be calculated with this and other method, and the results are almost the same.
