Based upon the beam theory of Winkler elastic foundation and the characteristics of the interaction between soil and pile, the discrete springs are used to simulate the interaction of soil pile. And the FEM method is presented to derive the stable equation of piles and calculate the buckling loads of piles. This method can be widely used and reach a certain precision, especially under the complex stress condition. The developed software system BR can be applied in practical engineering analysis.
