Abstract: To investigate the calculation of critical load for super-long pile widely used in engineering, elastical resistance of soil on the side of pile is taken into account. The soil resistance on the side of long pile is assumed to consist of two parts. By choosing suitable wrapping function of pile, the critical load is solved by Rayleigh-Ritz method, and then the relations between resistance model and the critical load and calculated length of super-long pile are analyzed. The result shows that the critical load of pile depends on the length of pile in the soil, reduction coefficient and other pile-soil system parameters.

Key words: super-long pile, double-linear resistance model, Rayleigh-ritz method, critical load
