TL;DR: In this paper, the authors present a framework to systematically investigate the high-speed train-track-bridge dynamic interactions, aiming to provide a method for analysing and assessing the running safety and the ride comfort of trains passing through bridges.

TL;DR: In this article, the authors presented an onsite experiment of the train-track-bridge interaction dynamics carried out on the Beijing-Tianjin high-speed railway, and then the experimental results are used to validate the train -track-bridges interaction simulation software (TTBSIM).

TL;DR: In this article , the authors proposed a vertical coupling dynamic analysis method of vehicle-track-substructure based on forced vibration and use this method to analyze the influence on the dynamic response of track and vehicle caused by local fastener failure.

TL;DR: In this paper , the deformation characteristics of super-span bridge and track in high-speed railway at the acceptance stage, the key factors to track static geometrics are identified, namely the route profile, surrounding temperature, construction deviation and ballast density deviation.

TL;DR: Based on long-term inspection data about track geometric irregularity of 32'm-span simply supported girder bridge in China Railway High-Speed for nearly 10' years, this article found that there is continuous periodic track longitudinal level (TLL) with different wavelengths, there are two types of variation trends for bridge creep and ballastless track slab upwarp are the primary reasons.
