Abstract
In order to reduce deformation of ballasted tracks during large earthquakes, a new method to reinforce ballasted tracks with stacked geosynthetic bags that are filled with ballast was proposed. In this study, based on results of shaking table model tests, it is confirmed that the reinforced ballasted tracks have a sufficient resistance against a seismic wave that is larger than the so-called Level 2 earthquake motions. Moreover, it is confirmed that improved versions of the reinforced ballasted tracks, such as piling bags with inclination and driving in a reinforcing bar with inclination, have a sufficient seismic resistance under a condition of the wide tracks on which a larger inertia force acts during earthquakes.
