摘　　要：夹桩器是海上导管架调平和灌浆的辅助工具。分析夹桩器受力及影响静摩擦系数因素,得出增大液压缸钳口表面粗糙度是增大钳口与钢桩间静摩擦系数的合理方法;并采用ANSYS有限元分析方法对夹桩器上均布液压缸数进行了选择。Pile gripper is the assistant tool for the leveling and grouting of the jacket, and its mechanical analysis is presented in this paper. Compared with the effects on equivalent static coefficient of friction, augmenting the surface roughness of the pincer is a rational method to augment the friction coefficient between pincer and steel pile. And the ANSYS finite element analysis is used to choose the number of hydraulic pressure vats, which are distributed in the pile gripper.
