Abstract：
In recent years, prestressed concrete tube pile was widely used in coastal area. But pile body floating problem was often detected. In practical project, completed earthwork excavation and support caused certain difficulties for retapping by static pile pressing machine. Therefore, stamping machine was adopted and it was proved that the bearing capacity and sedimentation of pile satisfy the specification requirements. Attention shall be paid to the application of prestressed concrete tube pile, especially when the building is high, spacing among pile is dense and there is thick saturated clay layer on the pile.
