Abstract  A time-domain solution of layered ground vibration due to moving load has been developed based on the thin layer method. Fourier-Laplace transforms are applied to derive the transformed domain solution that satisfies the boundary conditions of horizontal infinities. The eigen-decomposition approach is used with respect to the Laplace parameter, and the final ground response solution is constructed with the mode superposition method. The reliability and computation accuracy of the solution are proved by comparison with a closed-form solution. A single soil stratum on rigid bedrock is used to reveal the vibration features induced by a rectangular load moving at speeds below or above ground Rayleigh wave velocity.

Key words： Ground vibration      Moving load      Laplace transform      Eigen-decomposition
