摘　　要：针对一般预应力混凝土管桩施工中常见的偏位、开裂等质量通病,结合某桩基工程中存在的类似问题,分析管桩出现偏位、开裂的原因主要有定位放样有误、压桩速率过快、基坑开挖方法欠妥等,提出了处理问题的三种方法:整体牵引纠偏复位、局部混凝土芯桩补强和承台地梁加强,检测调整后部分基桩的承载力,结果证明达到了预期的处理效果。Since the deviation and cracking of prestressed concrete pipe pile are the typical problems existing in the course of construction, this article analyzes the causes of such problems combining with engineering practices, such as the error during the orientation, the excessive velocity of putting down the pile, improper method of pit-digging and so on, and then puts forward three methods for handling these problems. At last, after checking the bearing capacity of some piles, it indicates that these methods can achieves expectant effects.
