结合某广场工程PHC抗拔管桩的应用实例，计算了PHC管桩的抗拔承载力，介绍了管桩连接构件强度验算方法，并探讨了管桩与承台的连接方式，通过静载荷试验表明PHC管桩各项连接点均满足抗拔承载力的要求。%Combining with the application examples of a square engineering PHC pipe pile uplift example,calculated the uplift bearing capacity of PHC pipe pile,introduced the strength checking method of pipe pile connected components,and discussed the connecting way of pipe pile and pile caps,through the static load test showed that the PHC pipe pile each connection points meet the requirements of uplift bearing capacity.
