Abstract

In order to reduce deformation of ballasted railroads during large earthquakes, concrete blocks are currently employed. In this study, several performance evaluations are conducted on a newly proposed method to reinforce ballasted railroads with stacked geosynthetic bags that are filled with ballast, since it is more economical and efficient for construction than the concrete blocks. It is confirmed that the proposed method has a sufficient resistance as a seismic measures.
