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

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.
