Abstract :
According to the Winkler assumption, the form of the pile constraint could be simplified as bottom fixing and top free. Considering the influence from resistance of soil around pile, the equations on calculated length for buckling stability of steel pipe pile when the portions along the pile length were constrained in the uniform foundation and the layered foundation were respectively derived based on energy method and variational principles. and the application of the formulas was explained through examples. The equations are successfully applied in similar projects.
