The slipping pile is the phenomenon that the pile sinks for a long distance under a small hammering number or by the dead weight of a pile hammer when the pile penetrates into some soft soil layers. The large-amplitude pile slipping is not beneficial to construction control, and the normal construction procedures such as pile splicing, hammer replacement and the like are influenced by breaking a steel wire rope, breaking a pile hammer, breaking the pile and the like if the pile slipping is light; accidents such as the pile hammer falling into the sea, the pile hammer scrapping and the like are caused, and great economic loss and safety risk are brought to offshore operation.
