The large diameter cylinder pile with long tube is a kind of excellent pile type that developed in recent years which has good anti-strike and anti-bending ability,high durability and low cost.It can be replaced steel pipe pile in a certain range due to a strong ability to penetrate rock and sand.Taking the No.11 berthing project in Jiangyin Port,Fuzhou Port Area as an example,this paper applies the steel pipe pile,and the large diameter cylinder pile with long tube(composite pile of high strength pre-stressed concrete pipe pile+steel pile boots)as the foundation.The sinking pile is successfully completed.Compared with the traditional piles,the mechanical properties and cost of the long tube and large diameter cylinder pile have certain advantages.
