“…16, it is clear that it is the stiffness of the layer that is the dominant parameter, not its impedance as suggested by Massarsch [14] and used by other authors, e.g. [16,40]. In particular, materials B and E (see Table 5) have the same impedance but different insertion loss.…”

“…The fill material should therefore be much softer than the surrounding soil while being capable of balancing the surrounding earth pressure [14]. Common fill materials considered include bentonite, soil-bentonite mixtures [15], expanded polystyrene (EPS) [16,17] and other geo-foam materials such as polyurethane [18].…”

“…They concluded that materials with low impedance such as EPS geofoam are very effective in reducing the amplitude of waves. A centrifuge parametric study conducted by Murillo et al (2009) showed that the depth and the width of the geofoam barrier, as well as the location, have a significant influence on the ground vibration attenuation. A full scale experiment on attenuating ground vibrations generated by machine foundations using open and geofoam in-filled wave barriers was carried out by Alzawi and El Naggar (2011).…”

“…In order to approach amplitude reduction ratio provided by open trenches, different in-filled material has been tested. In particular, in [9][10][11] geofoam (expanded polystyrene or extrude polystyrene) as in-filled materials has been studied, while in [12,13] the use of gas cushions trenches as wave barriers is analyzed, obtaining results very close to open trenches performances.…”
