The 1995 Hyogoken-Nanbu Earthquake caused serious damage to conventional type railway abutments. They suffered large relative settlements between abutment and backfill, while even a small relative settlement would have endangered safe train operation. In this study, a series of shaking table tests on reinforced abutments with cement treated backfill were carried out in order to develop a new type abutment which can satisfactorily resist the high intensity of input motions such as that of Level 2 earthquake. The experiments revealed that the new type abutment was more stable than those of conventional types and they maintained sufficient stability against the very high intensity of input motion.
