Abstract：In order to study the bearing capacity of precast tubular uplift pile in sandy soil of Nanjing, based on the destructive field static load tests of eight uplift piles, it is analyzed the relation by compared four theoretical methods of calculating bearing capacity of JGJ94-08 standard formula, inverted truncated cone failure model, composite shear failure model and cylindrical failure model with the measured data. Meanwhile, fitting curves is carried on to analyze the load-displacement curves of test piles by hyperbolic function, exponential function and power function. Results show that the calculated bearing capacity of JGJ94-08 standard formula is much less than the measured value, and the calculated value of inverted truncated cone failure model is much higher than the measured value, cylindrical failure model is the only theoretical methods close to the measured values. In addition, exponential function fitting curve has high goodness of fittness and with the measured load-displacement curve and satisfactory effect.
