According to all of the technical standards in China, bearing capacity of prefabricated pile is calculated without taking into account the piling methods. But more and more engineering cases showed that under the same condition, the bearing capacity of pile foundation would be lower by hammer-driven than by static-pressure. The paper analyzed the difference from the soil mass and the effect on strength recovery after construction according to pile-setting mechanism, extruding function, pore pressure and dissipation.
