Abstract: First，the soil vibration model was established on the basis of considering the influence of tangential vibration on lateral vibration． Then，horizontal impedance of the soil amended was compared with the classical solution to proved that the solution proposed by the paper was corrected． Finally，horizontal impedance，rocking impedance and coupled horizontal and rocking impedance of large-diameter end-bearing pile were obtained by using the matrix transfer method． After detailed discussion of the parameters，it could be concluded that slenderness ratio and pile-soil relative stiffness were the key factors for dynamic impedance of large-diameter end-bearing pile，which showed that presented model could give more reasonable guidance on horizontal and rocking vibration of largediameter end-bearing pile．
