天津港北港池杂货码头工程中PHC桩的应用

Application of PHC Piles in North Harbor Bulk Cargo Terminal at Tianjin Port

天津港北港池杂货码头在天津港地区深水高桩码头建设中首次大面积采用PHC桩,根据本工程PHC桩的静荷载试验和打桩试验数据,通过与天津港钢管桩码头实际使用情况的对比,在总结设计施工经验的基础上,逐一研究解决空心桩内水的冻涨、PHC桩的抗冻能力和打桩控制标准等系列问题,可供我国北方港口其他采用PHC桩基的码头工程参考与借鉴。

A large quantity of PHC piles are firstly applied in Tianjin port north harbor bulk cargo terminal project in comparison with other deep-water piled terminals at Tianjin Port. Based on the static load test result and piling test data of PHC piles, by comparing with the application of steel pipe pile terminal at Tianjin port, the design and construction experiences are summarized to research water frost-heaving inside hollow piles, the frost resisting capacity of PHC piles and the piling control standard etc. which will provide references for the design and construction of China North terminals supported on PHC piles.
