Abstract: In this paper, on the basis of the analysis of nonlinear mechanism, we proposed a series calculated models for lateral loaded pile which describe the pile-soil coaction. Some concepts supposed in the paper are useful for reference, further study and application.

Key words: laferal loaded pile, nonlinear, composite stiffness
