摘要
文章介绍了冲孔灌注桩的形式分类与适用范围,并结合广西八甫大桥桥墩工程实例,分析了冲孔灌注桩的设计计算方法和施工注意事项。八甫大桥桥墩应用冲孔灌注桩技术后取得了良好效果,桩体质量合格率达到100%,承载力完全满足设计要求,经检测桥墩未出现下沉问题,可为今后类似工程施工提供技术参考。
This article introduced the form classification and application scope of punched cast-in-place piles.Combined with the pier engineering practice of Guangxi Bafu Bridge,it analyzed the design calculation methods and construction precautions of punched cast-in-place piles. The application of punched cast-in-place pile technology for the pier of Bafu Bridge has achieved good results,the pass rate of pile body quality has reached 100% ,and the bearing capacity has fully met the design requirements.After the test,the pier has no problem of subsidence,which can provide technical reference for the construction of similar projects in the future.
