预应力管桩缺损部位的加固方法

Re-Strengthening for the Defective Prestressed Concrete Pipe Pile

预应力管桩较其它桩型相比具有较多的优点,目前应用广泛。但是预应力管桩抗裂性能差,桩身容易出现裂缝,给工程造成安全上的隐患。结合工程实例,详细说明了预应力管桩缺陷部分的加固机理和加固方法,并从施工角度给出了合理的预防裂缝出现的建议。

The application of prestressed concrete pipe pile is pervasive because of its advantages compared to the other types. But the ability of pipe pile is to resist the bending is poor. Based on practical example, the authons of this paper particularize the method how to deal with the crevice and give some suggestions to prevent it.
