Screening effect of pile rows for ground vibration induced by moving loads

This study aims to predict the screening efficiency of pile rows in transversely isotropic (TI) saturated soils for ground vibrations subjected to moving loads. First, based on the fundamental solutions of TI saturated media, the boundary element method (BEM) was adopted to derive the force-deformation equation of the soil-pile boundary. The finite element method (FEM) was then applied to establish the stiffness matrix equation of the Euler-based pile rows. Subsequently, by coupling the BEM and FEM equations, the screening efficiency of the pile rows was developed according to the barrier isolation theory. The proposed approach was validated using published numerical results. Finally, the effect of soil stratification on the screening effect of pile rows in TI saturated soils was investigated.
