Abstract: Based on actual measured P-S curve, this article fits the curve to subsection linear function, and uses the slope of the function as bedding value. Then it derives the basic academic equation of variable bedding value elastic foundation beam; and changes it to the same equation form as constant bedding value elastic foundation beam. Having done that we can get the common results using the initial parameter method. This method can also be used in the case of variable cross-section beam and heterogeneous foundation.

Key words: Winkler’s hypothesis, subsection linearity, variable bedding value
