Testing Research on the Shape of the Bearing Push-extend Reamed Affecting the Bearing Capability of the Pile of Push-extend Multi-under-reamed Pile

摘要

As the shape of the bearing push-extend reamed can influence failure modes of the soil around the pile and below the disk, this paper, through experimental research that different shapes of the bearing push-extend reamed have influence on the capacity of the single push-extend Multi-under-reamed pile under the same loads, provides a reliable basis for further ascertaining the capacity of the push-extend Multi-under-reamed pile with the theory of sliding line.
