| Abstract: | Considering the three-dimensional wave effect of the soil pile,vertical vibration characteristics of the variable impedance pile is analyzed when the layered viscous damping materials in the soil pile is affected by any axial exciting time-varying force.And then the analytical solutions for frequency domain response,complex stiffness and velocity admittance are obtained.The influence of modulus change of soil at the bottom of the pile and impedance change in pile on the vibration characteristics of vertical... |
