누적통과톤수와 도상횡저항력과의 상관관계에 대한 연구

초록

One of the ballast in track component resists the force of vertical direction, longitudinal direction and lateral direction. In particular, lateral resistance of ballast is closely related to buckling strength. therefore the lateral resistance of ballast is important element to determine the track stability. But, the reduced lateral resistance of ballast and track strength threaten the stability of train operation because track maintenance-class 2 machine work and sleeper exchange- disturbs the ballast. This study find that it measures the variations in the amount of lateral resistance of ballast regarding to class2 machine work ballast cleaning. It realizes the restoring force characteristic of lateral resistance of ballast based on cumulative passing tonnage after calculating the cumulative passing tonnage and analyze correlation between the cumulative passing tonnage and the lateral resistance of ballast.
