PERFORMANCE OF REINFORCED SOIL SEGMENTAL RETAINING WALL UNDER THE SIMULATED TRAIN LOADING

초록

Geogrid has been widely used as the reinforcement materials in earth structures in order to achieve efficient land utilization as well as securing safety in railway service lines. Reinforced soil Segmental Retaining Wall (SRW) is a composite system consisted of SRW units in combination with a mass of reinforced soil stabilized by horizontal layers of geosynthetic or metallic reinforcement materials to enlarge the effective width and weight of the gravity mass. In this study, the static performance of geogrid-reinforced soil SRW was investigated through the real scale model test with the simulated train loads including the impact loading of train.
