摘要：
Analytical solutions of vertical dynamic impedance and amplitude amplification coefficient for vibration of rigid circular plate on saturated viscoelastic half-space were obtained by employing Hankel's integral transformation and considering mixed boundary condition of plate-subsoil interfaces to solve Boer's dynamic governing equations on porous medium. Furthermore, effects of liquid-solid coupling coefficient, mass ratio of foundation, and viscous damping coefficient of soil on vertical dynamic impedance and amplitude amplification coefficient of plate foundation were investigated by parametric comparative analyses. The solutions and results of vertical dynamic impedance and amplitude amplification coefficient of plate foundation derived in present paper are expected to contribute to theories on foundation vibrations and to provide technical reference and theoretical support for related engineering practices. ©, 2015, Tsinghua University.
