摘　　要：为解决传统托换桩方式存在的问题,文中以某公共建筑项目为依托,在传统一柱一桩托换方式的基础之上,采用桩柱一体化设计方案,通过规范施工前准备、底板切割开孔、钢筋笼制作安装、混凝土浇筑及养护四个关键环节,以确保桩柱一体化施工流程顺利进行;设计桩柱一体化监测试验,对不同试件进行分阶段加载位移监测,得到最大平均位移监测值为6.89 mm,满足设计规范要求。In order to solve the problems existing in the traditional pile replacement method,based on a public building project and on the basis of the traditional one-column and one-pile replacement method,this paper adopts an integrated pile design scheme to standardize the integrated pile construction process from four aspects:pre-construction preparation,floor cutting and opening,steel cage production and installation,concrete pouring and maintenance,and designs the integrated pile monitoring test.The displacement monitoring of different specimens was carried out by stage loading,and the maximum average displacement monitoring value was obtained to be 6.89mm,which met the requirements of the design specification and verified the feasibility of the scheme.
