摘要：The vibrations induced by the passage of high-speed trains(HSTs)are considered a crucial issue in the field of environmental and geotechnical *** wave barriers have been investigated to reduce the detrimental effects of HST-induced *** study is focused on the potential implementation of an innovative mitigation technique to alleviate the developed *** particular,the use of expanded polystyrene(EPS)blocks as partial fill material of embankment slopes was *** efficiency of the proposed mitigation technique was numerically *** specifically,a 3 D soil-track model was developed to study the cross-section of a railway track,embankment,and the underlying soil *** passage of the HST,Thalys,was simulated using a moving load method,and the soil response was calculated at several distances from the *** parameters influenced the effectiveness of the examined mitigation ***,to ensure an optimal design,a robust procedure is necessary which considers the impact of these ***,the implementation of EPS blocks on several embankments with different geometry,in terms of height and slope angle,was investigated.
