  • The pile-soil system is regarded as a visco-elastic half-space embedded pile.Based on the method of continuum mechanics,a nonlinear mathematical model of pile-soil interaction was established-a coupling nonlinear boundary value problem.Under the case of horizontal vibration,the nonlinearly dynamical characteristics of pile applying the axis force were studied in horizontal direction in frequency domain.The effects of parameters,especially the axis force on the stiffness were studied in detail.The numerical results suggest that it is possible that the pile applying an axis force will lose its stability.So,the effect of the axis force on the pile is considered.
