摘要
基于滨海地区某铜冶炼基地部分预应力管桩上浮问题的分析处理,对预应力管桩上浮机理进行了探究,给出了避免桩上浮的若干措施及上浮桩的处理方法,在该基地近万套预应力管桩的设计和施工中取得良好的效果,对处理类似工程问题具有重要的借鉴意义。
Based on the analysis and treatments on floating problem of the partially pre-stressed concrete pipe pile in a copper smelting base in coastal area and the analysis of the floating mechanism of the pre-stressed concrete pipe pile,this paper gives some measures to avoid the floating of the pile and the treatment methods of the floating pile,good results have been achieved in the design and construction of nearly 10000 pre-stressed concrete pipe piles in this project,to similar engineering has a very good reference value.
