Abstract
For preventing or reducing the damage of road embankments induced by sliding failure during earthquakes effectively and economically, the reinforcing and/or retrofitting methods based on the performance-based design are very important and effective, and should be developed as soon as possible in the near future. In this study, two types of structures named “Slope Toe Reinforce&Retrofit” and “Slope Failure Barrier” is proposed based on the new design concept proposed by authors, and the effects of these two structures are investigated for road embankment models by the centrifuge tests. As results, the mechanism of sliding failure of road embankments is clarified, and the effectiveness and applicability of the above new structures are verified.
