摘　　要：结合厦门地区某城市广场基础施工实例,对卵砾石层用作静压PHC管桩作为桩端持力层进行了探讨,分析了单桩抗压极限承载力不合格的原因,提出了施工中常见的问题及对策,总结了卵砾石层用作PHC管桩持力层的适宜性,具有一定的参考价值。Combined with foundation construction work of one urban square in Xiarnen the feasibility of gravel/cobble bed used as bearing course of PHC pipe pile is discussed. The reasons caused the unqualified ultimate compressive strength of single pile are analyzed; at the same time corresponding countermeasures are proposed. In the end the practicability of this method is summarized, which has a certain reference value.
