大管桩的组合桩在福建省的应用

The Application of Combination Pile of Big Pipe Pile in Fujian Province

结合福州港松下港区无洪3万t级多用途码头工程,在阐述大管桩的结构及其造价低、抗腐蚀性能好、承载力高和抗弯能力大等优越性的基础上,提出了一种新桩型,即大管桩与钢管桩的组合桩。并通过设计和施工的实践,证明大管桩组合桩具有大管桩与钢管桩的各自优点。

Combining the actual project example of Yuanhong Multipurpose Terminal of 30 000 DWT of Songxia Harbour, Fuzhou Port, the advantages such as low cost, good anti-corrosion character, high bearing capacity and high bending strength of big pipe pile and steel pipe pile were described in the paper. On the basis of that, a new type of combination pile namely, the combination of big pipe pile and steel pipe pile were raised in it. It was deseribed in the paper that the combination pile of big pile pile has the respective advantages of big pile and steel pipe pile, which had been proven by the design and construction.
