Research Abstract

This study examined a method to improve the structural stability of embankment against rainfall to increase of the disaster risk related to the climate change. Firstly, the factors affecting the stabilityof embankment during rainfallwere investigated by performing of a series of laboratory model tests. As a result, it was found that the stability of embankment during rainfallis strongly affected by seepage and surface flow. Based on the above findings, this study proposed a method that can be improved the stability of soil structure against rainfall by applying the combined technologywith geosynthetic-reinforcement and horizontal / vertical drainage.
