...Habib Shahnazari; Mohammad Kazemi; Mohammad Hassan Baziar This paper presents a centrifuge study on the performance of inclined geofoam barriers compared to a vertical geofoam barrier for the mitigation of ground vibrations induced by high-speed railways. Three different barrier inclinations (60...
