Notice of RetractionStudy on behaviors of lengthy pile in two-layer soil

Despite the long piles have been widely used, but this type of foundation of the load transfer mechanism is still unclear so far, long pile design calculation based upon the theory of ordinary pile, has not yet realistic calculation. Super-long pile is not the current standard design method based on super-long pile load-bearing deformation mechanism based on in-depth study, there is the contradiction between theory and practice, therefore, to carry out super-long pile bearing properties study and propose a reasonable long pile design approach is not only a theory, the need for self-development, but is also an urgent requirement engineering. In this paper, finite element model of long piles in homogeneous soil bearing characteristics.
