预应力管桩桩身倾斜事故处理工程实例

THE PROJECT EXAMPLE OF ACCIDENT TREATMENT OF STATICALLY PRESSED PRESTRESSED PIPE PILES'SLOPE

通过一实际工程,分析了静压预应力管桩斜桩产生的原因,提出处理斜桩的措施。实践证明通过对断裂斜桩及基础承台、底板的整体加固,并考虑上部结构———承台、底板—桩—土的综合共同作用来弥补因斜桩而造成的承载力损失是行之有效的处理方法。

In the light of a practical project, authors analysize the cause of pipe piles＇ slope, put forward the measure of dealing with sloping piles. The practice shows that it is effective to remedy the loss of bearing capacity due to sloping piles by reinforcing cracking sloping piles, foundation caps and ground board together, with considering of the cooperation of upper- level structure - pile cap trod ground board pile - earth.
