摘　　要：本文简要介绍了预应力高强混凝土抗拔管桩连接接头的形式。从施工工艺、受力计算分析和经济性三方面阐述三种连接方式在抗拔管桩应用的优缺点,说明了机械啮合连接接头施工简单方便,满足预应力高强混凝土抗拔管桩的工程性能要求,经济性较理想,相比其它连接方式,具有较强的优越性。This paper introduces the prestressed high strength concrete pile connector forms against uplift, and expatiates the advantages and disadvantages on the construction process, the force analysis and economic aspects. So, the mechanical mating connector is simple and convenient, and meets the engineering performance requirements of the PHC pile against uplift , and is economical. This form has more advantage compared with other connector forms.
