摘　　要：提出一种PHC抗拔管桩抱箍式连接方式,并分别通过理论分析研究和实例计算,得出了该连接方式的管桩抗拔承载力提高明显,连接处不易发生破坏。通过实际工程的应用发现该桩型抗拔效果优良,为工程应用中抗拔桩的设计选型提供一种更为便捷且造价节省的新桩型。A PHC uplift pile with hold-hoop connection is proposed. Through theoretical analysis and example calculation, it is found that the pullout capacity of the connection pipe pile is improved significantly, and the connection is less prone to be destructed. In the actual engineering application, the effect of pile uplift is excellent. It may provide a more convenient and economical type of new pile for engineering application.
