摘　　要：现代城市建设中,高层建筑、超高层建筑越来越多,而且多采用机械桩基础形式.机械桩基础施工时,往往存在地下水.在浇筑水下混凝土桩时,钢筋笼常常上浮.钢筋笼上浮影响了成桩质量,造成了高层建筑、超高层建筑的质量隐患.因此,探讨钢筋笼上浮原因及其控制措施,具有重要意义.文章对混凝土浇筑过程中钢筋笼受力进行了分析,对钢筋笼上浮的物理本质作了探讨,建立了钢筋笼上浮的数学模型,提出了钢筋笼上浮的控制措施.In the current unban construction, high-storey and super high-storey buildings are in the rise, and their foundations are mostly mechanical piles. In laying such foundations, underground water often gather. In pouring concrete piles, steel cage often float, which will reduce the fu＇mness of the piles and further becomes the potential source of poor quality of high-storey buildings. Thus the investigation of the analysis of force-standing of steel cage in laying, the physical essence of steel cage floating, the buildup of mathematic model of steel cage floating and the control measures of steel cage floating is of enormous value.
