In this paper, the application potential of expanded polystyrene (EPS) geofoam as a vibration screening material in an in-filled trench has been investigated under circular machine loading. Circular machine foundations are commonly used for the foundations of reciprocating engines, compressors, turbines, generators etc. The numerical analysis is performed using two-dimensional finite element method under dynamic condition. The present analysis considers the foundation bed as linearly elastic, isotropic and homogeneous soil deposit. The inclination of the trench is also considered as a special parametric study. The vertical displacement amplitudes of the ground vibrations are analysed at different pick-up points along the ground surface to determine the amplitude reduction factor (ARF).
