摘　　要：机械连接预应力混凝土竹节管桩是近年开发的一种新桩型,在工程中已得到应用。结合某工程实例,介绍因基坑软土开挖导致大量竹节管桩倾斜偏位甚至断裂事故的处理技术。现场试验及检测表明,传统纠偏法不适用于竹节管桩的倾斜纠偏,而采取小倾斜桩桩身补强、大倾斜桩补桩的处理技术路线是合理、经济和有效的措施。可为类似工程提供处理经验或参考。Mechanical connection pre-stressed concrete bamboo joint pipe piles is a new type of pile developed recently,it had been used in engineering practice. A case study was introduced on the technique for accident treatment of inclined bamboo joint pipe piles which caused by deep excavation in soft soil. Field experiment and on-site test showed that the traditional rectification technique was not suitable for bamboo joint pipe piles. A reasonable,economical and effective measure of treatment was to strengthen small declivity pile and filled large declivity pile. This case study can provide experience and reference for similar engineering projects.
