Abstract
In order to clarify mechanical performance of a new kind of steel piles with double pipe pile-shoe, bored steel tubular pile specimens and doubled steel tubular pile specimens were made and compression experiments were carried out. 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.
