Design of Pretensioned Prestressed Concrete Pipe Pile Used as Antifloating Pile/Yu Linjun (Hangzhou Branch,Beijing CCI Architectural Design Co., Ltd., Hangzhou 310014, China)
Abstract:Prestressed concrete pipe pile (PC pile) is widely applied in civil engineering projects.It takes full advantages of PC pile excellences when it is used as antifloating pile. Based on practical projects,the design details, calculation methods and structure formations of PC pile are introduced. The calculation methods of pile foundation's bearing capacity are analyzed, and the design suggestions are proposed. The calculation data and the experimental data are consistent. The results show that the design method is rational and economical.
Keywords:pretensioned; prestressed concrete pipe pile(PC pile); antifloating pile; static load experiment
