Analyzing Bearing Capacity Influence due to Location of Bearing Push-extend Reamed of the Push-extend Multi-under-reamed Pile

Because the failure behavior of the soil surrounding the Push-extend Multi-under-reamed Pile will be affected by the placed location of the bearing push-extend reamed, further, the bearing capacity of the Pile is affected, in the paper, through experimental study and theoretical analysis, it is qualitatively analyzed that the influence of the location of the bearing push-extend reamed for the bearing capacity of the Push-extend Multi-under-reamed Pile, the achievements of the paper will present the well theoretical basis for synthetically considering all of affecting factors in the design of the Push-extend Multi-under-reamed Pile.
