Abstract

In the paper, through use of ANSYS software of the finite element method to establish the simulation analysis model about the stress of soil around the pile, we obtained the normal and shear stress curve when the bearing push-extend reamed have different shapes under the same loads. It qualitatively analyzed the influence of bearing capacity on the push-extend Multi-under-reamed pile raised by the different shapes of the bearing push-extend reamed, and puts forward the theoretical basis that further promotes application of the push-extend Multi-under-reamed Pile.

 

Key words: Push-extend multi-under-reamed pile, shape of bearing push-extend reamed, dimension of diameter, bearing capacity of pile, influence.
