Abstract: | Three-dimensional (3D) transmission of vibration in an infinite elastic thin plate on a layer of poroviscoelastic medium,
due to a harmonic, rectangular moving load, is investigated theoretically based on Biot’s theory. The material of the medium
is idealized as a uniform, fully saturated poroviscoelastic layer on bedrock. By introducing four scalar potential functions
and Helmholtz decomposition theorem, analytical solutions of stress, displacement, and pore pressure with and without thin
plate are derived using Fourier transform technique. Numerical results are obtained with the help of inverse Fourier transform
and are used to analyze the influence of load velocity, porosity, permeability, relative stiffness of plate versus ground,
and the thickness of plate on the vibration. Furthermore, the results are compared with the available dynamic response results
of a non-moving load on a layer of viscoelastic material. |
