Influence of ballast shoulder width and track superelevation on the lateral resistance of a monoblock sleeper using discrete element method
Transportation Geotechnics(2023)
摘要
•The lateral resistance of a single monoblock sleeper was studied for different degrees of track superelevation and ballast shoulder width using the discrete element method (DEM).•The relative contributions of the base, crib and shoulder ballast to the lateral resistance of superelevated sleeper were investigated.
