桩基加大截面是一种较为理想的桩基础加固措施，水深较浅（5m以内）的可采用双层钢护筒的方法施工，但水深较深的桩基加固需要采用其他方法保证施工的安全同时减少工程成本。本文以江门市白藤大桥维修加固工程桩基加固（该桥位水深在8m到17.5m之间）为依托对水下桩基础加大截面的施工工艺进行分析研究，以期取得良好的效果，为类似工程的加固提供技术支持和工艺方面的参考。

increasing section reinforcement pile foundation is an ideal pile foundation, shallow water depth (within 5m) can the construction method ofthe protective tube of double steel pile, but deeper reinforcement requiredby other methods to ensure construction safety and reduce the cost of the project. This paper takes Jiangmen City rattan bridge repair reinforcementreinforcement (bit depth of the bridge in the 8m to 17.5m) for the analysis of underwater pile foundation construction technology section of relying on the increase, and achieved good results in order, to provide technical support and technical aspects of the reference for reinforcement of similar engineering.
