摘　　要：以某高速桥梁大直径桩基加固工程为例,为提高桥梁桩基的稳定性,提出公路桥梁大直径桩基加固补强施工技术研究。对大直径桥梁桩基进行植筋加固,进行模板制安及混凝土浇筑,最后对桩基裂缝进行封闭,以完成公路桥梁大直径桩基加固补强施工。结果表明,与未采用桩基加固方法相比,加固后,总计算沉降均有减少,证明该研究加固效果显著。In order to improve the stability of the bridge pile foundation,the large diameter pile foundation reinforcement construction technology of the large diameter pile foundation of the highway bridge is proposed.First,the pile foundation of the large diameter bridge is reinforced,then the formwork installation and concrete pouring are placed,and the cracks of the pile foundation are finally closed to complete the construction technical design of the large diameter pile foundation of the highway bridge.The actual construction results show that,compared with the unused pile foundation reinforcement method,the total calculated settlement is reduced after applying the proposed method,which proves that the reinforcement effect of this study is significant.
