PLUG EFFECT STUDY ON DOUBLE-PIPE PILE-SHOE OF STEEL PIPE PILES

摘要：

A new kind of steel piles with double pipe pile-shoe was designed and compression experiments were carried out. The influence of parameters on the bearing capacity, plugging effects and deformation ability are discussed. Experiments show that single pipe pile has no high performances and cannot get entire plug effect; Reinforced single pipe pile with ribs has higher performances and can get entire plug effect as the same as close-end piles; Double steel pipe piles have higher bearing capacity, entire plug effect and good ductility. A wedge shape of pile-shoe is helpful to form wedge effect and get higher plug effect, and a flat shape end of inner steel tube can get higher plug effect.
