论一种双向压旋抗拔桩的设计新方法

摘要

以提高桩的抗拔能力为前提，设计了一种新型的钢筋混凝土双向压旋抗拔预制桩，阐述了该桩的设计要点和运行流程，指出该桩构造具有压入旋进、抗拔的功能，适用于独立结构物的抗拔桩基础。%With the premise of improvinf the anti-floatinf capacity of the piles,the paper desifns a new reinforced concrete two-direction spinninf anti-floatinf precast pile,illustrates its desifn points and operation procedure,and indicates its functions of spinninf and anti-floatinf,so it can be adopted in the anti-floatinf pile foundation of the individual structural buildinfs.
