摘　　要：文中阐述静压PHC管桩施工工艺,结合现场静载试验,确定预应力高强混凝土管桩(PHC管桩)的竖向承载力与极限荷载作用下的沉降量,分析静压PHC管桩竖向承载力静载试验异常情况和处理措施,为该类型静压PHC管桩施工工艺及竖向承载力静载试验提供参考。By elaborating on the construction process of static pressure PHC pipe piles,combined with on-site static load tests,the vertical bearing capacity and settlement under ultimate load of prestressed high-strength concrete pipe piles(PHC pipe piles)are determined.The abnormal situation of static load tests on the vertical bearing capacity of static pressure PHC pipe piles is analyzed,and treatment measures are studied.This provides reference for the construction process and vertical bearing capacity static load tests of this type of static pressure PHC pipe piles.
