Surface Vibration of a Layered Saturated Ground Subjected to an Embedded Moving Load
Abstract The dynamic response of a layered poroelastic ground subjected to a buried moving load is analyzed by using the Fourier transform and the TRM method. Soil is idealized as a fully saturated poroelastic medium obeying Biot’s theory. A modified hysteretic damping model is introduced to describe the visco-elastic behavior of the soil. Using the Fourier transform and the inverse Fourier transform, the integral form solutions for dynamic response of a layered saturated half-plane under a buried moving load are obtained. When the layered half-plane is reduced to a homogeneous poroelastic half-plane, the results obtained in this paper are in good agreement with the published paper. At last, the vibration characteristics of three different cases in both frequency domain and time domain are investigated. And the influence of depth, speed and frequency of the buried load was also discussed by some numerical examples.
