Abstract
Conventionally, an inspection method to evaluate stability of railway retaining walls is basically visual inspection. This is because there is no quantitative inspection method. Therefore, a percussion test which is commonly applied to bridge substructures to check its stability was applied to the leaning retaining walls for investigation of their frequency characteristics. Subsequently, to indentify the relationships between the integrity and frequency characteristics of the retaining walls, a series of model tests was conducted. Consequently, a newly developed stability inspection and evaluation methods were presented, and successfully verified to apply to existing leaning retaining walls.
