DOI: 10.1016/j.conbuildmat.2021.122245
Abstract: Abstract Ballast and slab railway track structures are constructed from different materials, thus requiring different maintenance strategies. Therefore, this paper compares the settlement performance of both structures using laboratory experiments, and calibrates numerical models based… read more here.

DOI: 10.1016/j.trgeo.2017.06.003
Abstract: The damage detection and repair control have become important tasks for ballast and slab tracks. Measurements which compare the damaged and the repaired status of the same track section at different times, or which compare… read more here.

DOI: 10.1115/1.4047087
Abstract: Various vibration-attenuating slab tracks have been introduced into urban railways to minimize the negative effects of train-induced ground vibration and noise. However, compared with traditional slab tracks, vibration-attenuating slab tracks usually have a lower overall… read more here.

DOI: 10.1177/0954409719835036
Abstract: The characteristics of train passages over intact or damaged slab tracks on different soils have been calculated by the finite-element boundary-element method or the wavenumber-domain method. The influence of track and soil parameters on the… read more here.
