Short summary
The number of occurrences of ground subsidence induced by a leakage of aged pipelines for water and sewage in urban areas resulting in various sizes of cavity near the urban railway in South Korea has increased and it may cause roadbed settlement to exceed the allowable value. In this study, a three-dimensional numerical analysis is carried out to estimate roadbed stability and its risk level associated with various groundwater levels and sizes of cavities in simulated ground conditions.
