Static Behavior of Geotextile Container for Urgent Restoration of Rail Roadbed

Utilizing of the geotextile container shows several advantages such as standardized construction, factory manufactured products, the control of quality, workability, and economical point of view. Recently this technique can be applied to rehabilitate the loss of rail roadbed due to the heavy rainfall. In this study, a large-scale laboratory test were conducted with simulation of static performance on the geotextile container reinforced rail roadbed. Based on the laboratory test results, the vertical pressure distribution with respect to the depth, and settlement of rail roadbed were measured and compared test results between geotextile container reinforced case and unreinforced case. Thus, the effectiveness of reinforcement was evaluated in terms of its performance and stability.
