Before the operation of newly constructed railways, tamping and stabilizing machines
should be used to improve the quality of ballast beds. With the expansion of the railway …

Under high-frequency impact loading, the ballast bed is prone to ballast crushing,
deterioration, and other adverse effects. The use of elastic sleepers is an effective way to …

To analyze more accurately the dynamic response of sleeper and ballast bed under heavy
haul railway train load, this paper uses parallel bonded spherical elements to simulate …

The buckling potential of continuously welded rails poses a significant risk for traffic
accidents. This risk has become more pronounced owing to global warming. In ballasted …

使用大型捣固车对有砟轨道进行作业, 是改善道床质量状态最有效方法和通用手段,
是保障列车安全运营的必然选择. 但我国大型养路机械源于引进国外技术 …

Railway tracks must resist lateral horizontal forces associated with curving and wind loading
of trains and provide lateral restraint to prevent rail buckling in hot weather. On a ballasted …

The under-sleeper pad (USP) is extensively used in railway track structures due to its
desired damping performance. The impact of USP on the stiffness and dynamic responses …

The tamping process is crucial for correcting geometric irregularities on railway tracks,
especially on newly constructed or renovated tracks that are more susceptible to …

Utilizing large tamping vehicles to maintain the ballasted track is the most effective method
and general mean to improve the quality of ballast bed, which is also the inevitable choice to …
