The analysis of mud pumping which causes track irregularities during softening of present roadbed is needed in order to prepare countermeasure that is efficient and reasonable against the softening of railway roadbed. In this study, model tests were performed in order to evaluate property of the railway softening under the train loading, considering the wheel load and the impact coefficient due to the train passing velocity. The existence of the mud pumping, settlements of roadbed and vertical earth pressure were measured under the train loading.

The objective of this study is to suggest the optimal method for reinforced earth retaining wall through the appropriate selection of reinforcing materials, development of design criteria. Thus, the efficient land utilization and securing safety in the train operation in service lines could be achieved. For this goal, a large scale shear laboratory test was carried out to evaluate the reinforced effect of earth body reinforced by attachment-type geogrid.
