Changes in Material Properties and Damage Mechanism of Plate Ballastless Track Under Fire and High Temperature

Buildings
The service status of rail, fasteners and track slabs is the key determinant of whether the ballastless track is ready for traffic after a fire. The track slab rail support bolt anchoring performance and the shoulder service performance damaged by fire ...

Temperature Features of CRTSII Slab Ballastless Track in Severe Cold Region

DEStech Transactions on Engineering and Technology Research, 2017
Damages, such as slab end warped, gaps of slab and bed, and cracks of track bed, of CRTSII Slab-Ballastless-Track (SBT) in high speed railway were studied for temperature changing significantly in severe cold regions. First, Contact-Thermal- Resistance (CTR) between Concrete-Asphalt (CA) mortars of the SBT and roadbed were defined.

Efficient quantifying track structure cracks using deep learning

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 19, Page 2969-2986, 5 August 2025.
Abstract High‐speed railway ballastless track structure crack detection usually has a high demand for the efficiency of crack detection technology. To overcome the limitation that current crack quantification methods usually require multiple steps, this paper proposes an efficient quantification method for track structure cracks using deep learning ...

Parallel computing aided analyses of dynamic buckling for railway track infrastructure

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 19, Page 2943-2968, 5 August 2025.
Abstract This paper presents a scalable parallel computing framework for simulating track buckling under dynamic train loads, enabling large‐scale railway track stability analysis. A three‐dimensional (3D) track model is developed using finite element‐based Euler–Bernoulli beam formulations for rails, dynamic force inputs, and nonlinear interactions at
