In this paper, the combined method of 2.5D and 3D boundary element techniques is developed for the numerical analysis of the moving load problems with 3D configurations. Firstly, the boundary element method is presented for 2.5D problem with 2D geometry subjected to the moving load. Secondly, the 3D BEM analysis for the scattering problem by a finite barrier is carried out using the 2.5D solution as an incident wave field. The combined method is used to investigate the effectiveness of vibration reduction measures like a vibration barrier. Numerical examples for 2.5D and 3D analyses are compared to see the effect of the finite trench on the scattered field on the surface. It is shown that the combined method of 2.5D and 3D BEMs is useful for the analysis of a finite barrier subjected to the moving load.
