STUDY ON ESTIMATION METHODS OF PILE PRESSURE OF PRESTRESSED PIPE PILE BY STATIC PRESSURE METHOD
Taking Ruicang Expressway as the case,pile pressure estimation methods of prestressed pipe piles by static pressure method are compared. Four typical empirical formulas of pile pressure are selected for comparative analysis by using measured data and calculation results. The estimation formula that is most consistent with the proj-ect is determined. Combined with the bearing capacity calculation formula in the code,the empirical relationship be-tween bearing capacity and design pile pressure is obtained,and the design pile pressure of different design pile lengths in each bid section is finally determined.
