| Abstract: |
| Based on Biot's wave equation,we obtain the analytical solution of saturated foundation in the wave number-frequency domain and time-space domain by Fourier transform and inverse Fourier transform.Then,the propagation characteristics of the wave in the saturated porous elastic foundation under the action of moving load dynamic response studied by means of method.The dispersion curve,Doppler effect,composition and are frequency characteristics are analyzed.It is found that the saturated soil foundation has a more fluid medium than elastic foundation,and the fluctuation characteristics are obviously different from an elastic medium. |
