预应力管桩上接沉管灌注桩组合桩设计

DESIGN OF COMPOSITE PILE OF PRESTRESSED PIPE PILE AND CAISSON PILE

通过对宁波早期预制方桩与沉管灌注桩组合桩工程应用调查与分析,结合现在预应力管桩与沉管灌注桩成熟的施工工艺,提出了采用预应力管桩上接沉管灌注桩结合的新组合桩型,对预应力管桩上接沉管灌注桩组合桩型施工工艺与构造设计提出了建议。

Through investigation on the project application of the previous composite pile of precast pile and caisson pile in Ningbo, and combined the construction technology of prestressed pipe pile and caisson pile, it is advanced a new composite pile of prestressed pipe pile and caisson pile, and some suggestions on its construction technology and structural design are also proposed.
