摘　　要：结合具体的工程概况,对其工程地质作了阐述,探讨了将卵砾石层用作静压PHC管桩持力层的适宜性,并对桩基施工及检测作了介绍,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其对策。Combined with practical work the general situations and engineering geological conditions of this work are introduced. The feasibility of using pebble bed as bearing stratum of PHC pipe pile is discussed. In addition the construction and inspection of pile foundation are introduced. The reasons caused the unqualified ultimate compressive bearing capacity of single pile is also analyzed; at the same time corresponding resolving measures are presented.
