Abstract Firstly, the static forces of multipoint and iso-pressing pile holdermechanism of hydraulic static pile driver were analyzed. And then the computation formula of pile holder force of each two-piece clamp and perpendicular acting force between each two-piece clamp and hydraulic static pressed precasting pile were obtained. Finally, research and analysis on this formula are carried out, whose conclusion is beneficial for design and use of multipoint and iso-pressing pile holder mechanism of hydraulic static pile driver.
